Lets hope they do put a lot of effort into the Wii version cos I think it's success depends on it. There's no argument that Sonic sells better on the Wii as sonic's 2 most successfull titles (not including SSBB) were written for the Wi and there's over 5M sales yet if you look at it's least successfull titles their all ports even though they sold more than all of their other multiplat equivelants added together.
It makes no sense to me (and hopefully to Sega) to give the Wii a port of a game that will clearly be trounced in sales and ignoring Wiiconnect24, online, Wiiware, motion control features - especially as Rol has already pointed out that the engine is in place with Sonic and Secret Rings, a game that has been in the WW charts the longest for Sega and is still consistently racking up sales on a weekly basis - it just wont die.
The Wii will be the lead platform I feel and it may be the last Sonic game the PS360 get.
