Screenshots indicate the inclusion of Tails’ airplane, Metal Sonic as a boss, Christmas avalanches, classic special stages, and an uncanny variety in stage concepts. You can view the complete batch over at the game’s official page on the Xbox website.
Expect to see the completed game at some point this year, but no firm date has been announced. It does look like development is taking off, though.





I haven't played the first, but seen mixed things about it – is it worth it?
To be honest, it's pretty expensive with not much content, uninspired levels, and weird physics compared to the classic games. Not totally "bad", but it's no Sonic 2.
This one looks like it will address issues with the original, or at least the more vocal complaints, so I'd say wait for this.
It doesn't seem worth it too me, Generations provided more content at a relatively cheaper price so I would stick with that.
