I think you're way off base on that one there.
I sincerely doubt Birth by Sleep and Coded will get a port to the Wii any time soon. It took a few years for them to remake Chain of Memories for the PS2. Keep on dreaming, I think.Not only does the KH team have to finish with Birth by Sleep and Coded, if I am right about the Wii version of I & II they'll have that to port to the Wii too. Also, if I recall correctly, part of the KH team is working on FF vXIII and that's not done either. So I think we'd have to wait at least another year or more until more progress has been done with Versus before we even get a smell of a true sequel to the series.
At any rate, the FFvXIII comment is accurate. The team developing FFvXIII is the Kingdom Hearts dev. team, so don't expect to see any progress on KH3 until they've got that one in the bag.
