I really don't think he's entirely to blame. I believe that he does actually care; he's working the tourney scene hard and I think its because he knows that is how to bolster the popularity of a fighting game in Japan, which is where Namco will look first for progress. I think he got shafted by upper management and just not given the time to do things right. That's just my take on it anyway.
My opinion on what they should do.. put back the missing characters that don't have analogs, as I said. They probably shouldn't change story mode but they should finish it at least, incorperating what they had and the info from the Japanese SCV artbook, if not as arcade endings then perhaps in a museum mode where you could look it up. Include all the 1p/2p equipment that they didn't finish releasing, and re-open the Cepheus store with more stuff down the line. And they should examine all the info they've gathered through all the tourney's theyve done so far and consult with top name players to balance the hell out of the new and existing characters. The Super version should also come as a standalone release as well as a reduced price DLC upgrade for those of us who bought the game already.
I think that scenario would quiet just about all the complaints. It wont satisfy everyone, obviously, but short of a whole new game that's really about the best we could expect from them.
