Official Site is up! It's pretty much the same thing though and no new screens that I can tell of, but it's up.
Here's a video montage of upcoming PSP games, including Rivals 2. It looks pretty interesting, and you can see Tails being played in it too.
IGN has an interview with BioWare about the upcoming Sonic game. Seems they are very focused on this game, which I know will make everyone happy.
IGN has a new preview article of this game up along with some new pictures and 5 videos. Included is news that there is some branching paths and that, although we can't control the camera, the camera is good in this game-these among other things.
I was on GameFAQS, and someone found what appears to be screenshots of 2 mini-games. One that shows Sonic, Knux, Amy, and what looks like the genie in a fiddle contest, and another that show the characters in front of balloons doing something.
Also, apparently this game has already been rated E, which seems like it got rated awfully fast compared to Shadow, Riders, Rivals, and StH.
