For the record apart from the placement of the two arcologies there is also the following issue:
The other detail that was wrong was the Redmond Barrens. If you look at that previous map, about 1/3 of the way down on the right side, you’ll see a big park and regular suburbia…but that’s not remotely the wasteland that is the Redmond Barrens. This map appropriately takes that into consideration.
Unfortunately the map doesn't show all of Seattle Metroplex, which is not a problem in itself, but seems to have lead to the wrong conclusions. The "corrected" area is actually right in the middle of Bellevue. Redmond isn't really on the map, except for a small area in the upper right corner. It's further to the east. In addition, though I guess that's open to interpretation, this "rubble look" to me seems more suited for Puyallup.
As a remark for the issue of the two arcologies, both are not only placed right in the first edition, but especially the Renraku arcology's position has been reaffirmed by many Canon references. For example its connection to the Seattle Monorail:
http://shadowrun.wikia.com/wiki/Seattle_Monorail Or Renraku Arcology: Shutdown p.12-13 which had this to say about the view from the arcology:
[..] the same massive windows that let in the sunlight also provide a spectacular view of downtown Seattle or, on the building's western and southern sides, Elliott Bay.
I suspect that the placement is based on the various covers, probably the cover of Native American Nations Volume One. Unfortunately those have never been accurate (admittedly it's hard to do as the Renraku arcology is actually five times taller than the Space Needle).
Out of curiosity, what does it really matter? For the board game, doubt that some of the specifics you're referring to will actually have any impact on the game. I do appreciate the "continuity" issue, but just not seeing why it's such a big gaff (IMHO).
It could matter for Shadowrun itself. See this older tumblr post:
