To reiterate what ds was saying, this isn't a thread about what is/will be worth collecting on the Wii. To put it another way: "What Wii games should you buy right this minute if you see it for a decent price, because it's going to sky rocket in value, or be almost impossible to find locally in a collectible condition."
Sonic Colors is not one of those titles. Mario games are generally nowhere near rare either, but they have Mario in them, and as such they command a lot of recognition from both buyers and sellers. So yes, Super Smash Brothers will most likely hold at least the $40 mark down the road. However, there are only three Sonic titles that I can think of that you'd have to pay more than twenty dollars to get complete, and two of them are imports. Sorry to be so curt, but Sonic Colors: Not going anywhere in price.
