I think Full Frame will continue to move down in the DSLR market as the sensors continue to get cheaper. Why do you want a slightly smaller sensor? With the smaller volume, it would probably be more expensive than the FF sensor. There is already a $2000 FF body with the ability to shoot in 'APS' mode at 11MB for those times when you don't want the large files or whatever. This is the future as I see it. - TF
