Very good news indeed. The Obi-Wan figures from these movies have been somewhat lacking. Especially from THE PHANTOM MENACE. Figure sculpting and articulation has come such a long way from that 1999-2001 period, and that's when we got the bulk of our EPISODE I Obi-Wans. Everything since has pretty much been a kitbash. I'd be very interested in seeing an all new TPM Obi-Wan that's been built from the ground up by the current Hasbro Star Wars team.
The ATTACK OF THE CLONES Obi-Wan will probably be based around the ROTS Pilot figure, but with different paint apps. A new headsculpt is the obvious difference, as are the boots.
As for ANH Obi-Wan? That one might prove the trickiest to pull off, given the nature of his Jedi robes. But if it's done with softgoods similar to the ROTS Agen Kolar, I think it will go over pretty well.
