Well, the version of for the iPhone came out a few days ago and the Wii version comes out tomorrow, 10/11/10 and will cost 1500 points or $15 USD w/o tax. The initial reviews so far indicate that it is essentially a remake of the original versions of the game with newer graphics and sound. The Wii version is limited to standard definition while PS3 and XBox users will get the full HD versions. Unfortunately, it sound like it it little more than a remake but at $15, you can’t really go wrong. Hopefully SEGA takes the hint and makes future episodes a little more evolutionary.
