Yeah, seeing the 10 minute new-features video that the DailyDL has, i cannot ignore this title. Capcom has obviously put in an incredible amount of thought into what features needs to be into the game to please everyone - casual and hardcore - as much as possible. It's really sick. Trials, challenges, screen filters (or lack thereof), easy button setup, GGPO, great matchmaking, uploading to youtube, in-game based achievos, etc; I am impressed.
For $15 bucks, this is easily worth anyone's money if you like the older, faster paced Street Fighter games. I pretty much went from not interested to day 1 purchase after hearing about this stuff.
I'll have to find my PS2 version and dust up on Urien.
