Nicky Hayden, who initially seemed set to leave MotoGP for WSBK, now appears to be the main target for teams seeking to run the new range of Honda or Yamaha privateer MotoGP machines in 2014.
Speaking at Brno on Thursday the former world champion, who has lost his factory Ducati ride to Cal Crutchlow, was unable to name his future destination - but did reveal he has been surprised by the 'exciting' options available.
"I really can't [tell you anything about 2014]. Even I don't know yet. I'm not just giving you a line," began Hayden.
"It does look exciting actually. A month ago I didn't know I would have this many options - some good options too. Some that are quite exciting, that have really got me looking forward to the future.
"These next few weeks are the crunch time. Still some details to work out, to find which choice seems like the best for me. But I can say that I'm pretty excited and looking forward to what's next and see what I got left."
Asked to confirm if his preference is to remain in MotoGP, Hayden replied: "Yeah my heart is still in MotoGP, so if I can find the right home here on something that sounds like fun and sounds competitive, I'll stay here.
"WSBK is maybe not my first choice, but there's worse choices than going there on a factory bike. So I have some negotiations on both sides and we'll see what shakes out. We'll know in the next few weeks."
Hayden, who clashed with team-mate Andrea Dovizioso
at the final turn of last Sunday's Indianapolis round, has taken a best race finish of fifth so far this season.
