It's pretty clear that Bioware doesn't care anymore. Let me give you my perspective on Bioware and "dev realities."
My wife is a big Mass Effect fan, and played the first game on the 360 in Japanese. So when it came time to play ME2, she got it for the 360 as well. There was no Cerberus code, and they were going to release all the extras via the Market, free and paid. Well, it never happened. They released the Kasumi DLC, and it was totally bugged, crashing the game from the word go. So they pulled it off of the Market, back in August. No information came out until early this month, when EA Japan revealed that the downloadable content for ME2 on the 360 was cancelled, because Bioware refused to work on it. They had "moved on" to ME3. So 360 users in Japan are screwed, they got nothing. Even though everything is available for the PS3 version of the game.
My wife hates Bioware now, and I'm sure there are a whole bunch of hardcore 360 players in Japan who won't trust Bioware again.
Dev realities, right Bioware? They don't care about the fans that represent a "minority," be they Japanese 360 players or PC players. It's all about the numbers, and not developer pride at this point.
