They probably needed a lot of people to shift focus on FFXIII in order finish it in time for the release date. Recently they added that they've improved their development techniques meaning any future FF games would be completed much faster.
That being said after FF13 is released they will all most likely move onto FF13vs. They also won't need to worry about X360 version. I can see a 2010 holiday release in Japan and March 2011 in NA.
I agree with everyone that said that they wouldn't want to steal any press from FFXIII
