Ah, you saw this as well, I see... Good thing I didn't post it.
I didn't really watch the video when I came across it (buffering!), but I got the general idea. Although a lot of people have been criticizing this game for not having amped-up enough graphics... whatever, people. This isn't PGR, or anything--you're not going to have realistic rain hit your realistic windshield while you realistically veer into a guardrail and explode (realistically). For a game with cartoony people driving karts (which are resembling actual go-karts less and less with every installment) it looks great.
