We'll certainly see many 250 riders move on to Moto2, but there are MotoGP riders making the switch the other way, at least one coming from World Superbike, and even a few moving all the way up from 125s. Only one American is entered at this point: Spanish championship regular Kenny Noyes. The situation with the teams is similar, with MotoGP regulars such as Tech3 and Gresini signing up to join long-time 250 teams like Aspar and Scot, plus some altogether new outfits. There have also been some drop-outs, as would be expected with new teams looking at new rules and trying for new sponsorship dollars. Aprilia decided it wasn't in its best interest to campaign bikes with Honda engines, while Pramac decided it had a full enough plate with MotoGP.
