Of course, that's understood. The Blizzard release version would be better by several orders of magnitude.
My point, ultimately, is that the game already exists. That leads to a reasonable conclusion that the design pipeline wouldn't be as long for a game that doesn't exist, particularly given the resources that are at Irvine. People concluding that it wouldn't therefore take several years, are being pretty reasonable.
Would you mind quickly sourcing what commentary you're referring to?
Just the most recent examples of official commentary will be fine.
Thanks in advance.
