I don't have a problem with FF X and X-2 being separate on Vita. Geez. I always suspected it was because they wouldn't fit on one Vita card. FF VIII alone is ~ 1.4GB, the bloody PS1 game. I didn't see how two HD'd up PS3 games would be able to fit. I know, I know "Metal Gear Solid did it!"; but I guess they're just much smaller games than your average Final Fantasy.
Speaking of which, there was a video for Dragon Fantasy Book II in that blog post. Looks awesome!
