Well, even the Dark Horse and New Essential Chronology maps take the Run past Corellia, even though it doesn't make it to Coruscant.

However, text evidence does have it going all the way there, e.g. on page 8 of Coruscant and the Core Worlds: "The planet found itself at the confluence of a number of lengthy hyperroutes - including those later named . . . the Perlemian Trade Route, and the Corellian Run." Also, The Slice (and the Arrowhead, as defined on p. 5 of the New Essential Chronology) is defined by where the Corellian Run and the Perlemian Trade Route come together, which doesn't occur with the former melding into the Hydian Way.

Currently, my main complaint about the most recent maps is that the Corellian Run connects with the Hydian Way instead of with Coruscant, which you've mentioned earlier as unintentional.
Hmmm, maybe I was corrected at some point. All my sources indicate that the Corellia Run starts at Corellia. I'm not even sure if the Corellian Trade Spine goes to Coruscant. This may have been a revision form earlier maps. Going strictly by text descriptions, the routes on the Dark Horse map (based on the routes as shown in the New Essential Chronology map) look accurate to me.

When is the SW Atlas going to appear so we could finally have definitive locations?
Nothing in the works.

*Also, the map is wrong in assuming that Bespin and Hoth are in different solar systems.
There are two answers to this...*
ESB tells us that they aren't in the same system. Hoth is in the Hoth system. The Falcon is later in the Anoat system. By Leia's response, we can assume that Bespin is in yet another system.
The backup hyperdrive from the Essential Chronology is the in-continuity explanation.

Tasty is Concord Dawns location correct on the Dark Horse map?
I don't have any sources detailing the borders of the Mandalore sector, so the placement doesn't conflict with anything previous. Could just be the Mandalore sector follows a lesser known hyperspace lane.

If might be good for the next map to show sectors in full
This is a bit tricky, because there are multiple definitions of sector.
Essential Guide to Planets and Moons: The original definition of a sector was any area of space with fifty inhabited planets, but increased exploration has caused many sectors to grow far beyond their original boundaries.
Imperial Sourcebook: A group or cluster of star systems united for economic and political reasons. Doesn't say that the sector has to be contiguous.
Also, because the galaxy has been so unstable for so many years, the sector borders are very elastic.

*EACH of these maps is supposed to be "definitive," yet each, to my knowledge, has erred in some way.
I just wish all the SW sources would agree with eachother.*
We are always striving to improve which I created this thread. Keep in mind the context of each map is usually different, so sector and region borders might change. Seems strange to me to consider portions of the Unknown Regions as still unknown 100 years after they became known.

Tasty is Concord Dawns location correct on the Dark Horse map? From what I remember it was apart of the Mandalore Sector in A Practical Man, at least that's what the E-novella said. However the space between the two planets does make the Sector quite a bit bigger now.

If might be good for the next map to show sectors in full, so that we can get a better picture of how big sectors like the Mandalore Sector really are.

Also, the map is wrong in assuming that Bespin and Hoth are in different solar systems. In many Star Wars books, they empathize how long it takes just to travel within a solar system without using the hyperdrive. Even if the Falcon was capable of sub-light speeds of up to 1/2 the speed of light (any faster, and Relativity and all its weird effects start to kick in), it would take it years to get to another solar system.

Therefore, unless the Falcon slipped through a wormhole in the Hoth Asteroid belt that no one noticed (and I don't mean the hole in the rock caused by the Space Slug) Bespin must be in the same solar system as Hoth.

To be honest, I'm getting a bit tired of all these maps. Every map contains differences compared to the other maps! This just look like maps from the Middle Ages with Dragons and other fantastic creatures that were supposed to live in the seas and uncharted lands. When is the SW Atlas going to appear so we could finally have definitive locations?

Sure. If you look to the right of Hutt Space, you'll see a region of space labeled the "Tion Cluster." The Tion Cluster contains three different sectors - the Cronese Mandate, the Allied Tion, and the Tion Hegemony. The Tion Hegemony is roughly the rightmost third of the Cluster.

Dark horse plans to put it online and make it interactive.

O.J.:

*I got a copy without having to go to Comic-Con to get one.

:D*

Yeah, well, I also got to meet Abel Pena, Dan Wallace, and Joe Corroney, and get autographs on Insider 66 and the New Essential Guide to Droids; listen to the Legacy of the Force panel; see Ray Bradbury and Ray Harryhausen talk; buy old gaming books; and spend quality time with a girl I'm very much enjoying getting to know better. So now who's got the big Yoda smile, hmm?

As did I, and Modi your maps blow me away every time I see them.
