I honestly don't see why Sega and Nintendo do not capitalize on the Mario and Sonic crossovers. So far, the only game they've been in together, besides the Olympics games, was Super Smash Bros. Brawl. And that's sad. Why are they limiting themselves to games that will only come out every four years?! It doesn't make sense! That would've been cool (and a little weird) to see Mario in the Wii version of Sonic and Sega All-Stars Racing. AND Nintendo could've used that opportunity to promote Mario Kart. Sega and Nintendo need to expand on the Mario and Sonic crossover series. The world can only take so many Olympic games before they start wanting something more.
