its wierd seeing Silver and Yoshi giving eachother high fives. besides that the series has good opening graphics
I like the Sonic Mario concept but olympic games?? Save that for an actual sports game instead put Mario and Sonic in an adventure.
The other major new things added are online play. Balance board support (optional) as well as customizable options for snowboards, skiis and even your Miis outfits.
I do not see anything "new" about this trailer as I have seen it weeks before. It seems that Bowser Jr., Donkey Kong, Metal Sonic, and Silver the Hedgehog are the new playable characters, while there are other new, but unplayable characters who act as bosses not mentioned in this trailer.
