No to a 3 man factory team, but there has been some mumbling about 4 works bikes remaining with Dovizioso going to LCR with one of them. The rumors I've heard, which have roughly as much value as the electrons in this message, place Stoner and Pedrosa with Repsol, Simoncelli (factory bike) and Aoyama with Gresini, and Dovi to LCR with a factory bike, no idea if it's a one or 2 rider team.
Yamaha has Lorenzo and Spies signed, Crutchlow will stay at Tech 3, possibly along side Bradl. Edwards theoretically has 'a plan' for next season, but whether it's in GP, SBK or at the boot camp, no idea.
Ducati, Rossi and Hayden both signed, Abraham will (deservedly) return, from there I have no idea. There were rumors that one of the satellite Ducati teams is talking to Honda (can you blame them?).
Suzuki has not even confirmed that they will be there, although the last rumor was that they are coming with the 800cc bike. If so, I guess they hope to beat the CRT bikes.Bradl and Iannone are very possible (from the rumors Bradl is almost a given). Strong Hopkins to return rumors, hard to say but I hope that it's true. Elias, Capirossi and RDP all rumored to be shopping around the World Superbike paddock but I would think that Capirossi will retire. He has over 300 GPs under his belt and the old fire doesn't appear to be there.
I don't expect Smith or Marquez to move up yet, but if not they will make for interesting rumors in '13 if they maintain their form!
None of this is worth much...
I really hope Suzuki stays with it - prefereably with a 1000'er, but if not then at least with the 800. Right now they're running at the front of the non-factory- hondyamahs. CE still there in 2012 would be a surprise for me - he's a great guy, entertaining &&&&, but consistently finishes behind his qualifying position
