I am not sure that the new XV workstations will have huge touch-screen. Roland seem to be quite conventional here. The XV-88 even has a two-liner! That is a bit too old-fashioned, IMHO. The VA is a totally different instrument, and may have a totally different design from the new XVs.

Unit cost is an extremely important issue here. Roland would probably not want the workstation to be too expensive. That could mean bye-bye user-sampling. Or they may release several versions with more or less features.

I think the new XVs will look much like the XV-88, only with 61/76 semiweighted keys. Because of the complexity of a workstation compared to a "normal" synth, it will probably get a bigger display. The other capabilities would probably be on level with XV-88/3080. Perhaps a few more expansions.

It would be typical for Roland if they had a sound-module (XV-5080) as their most advanced synthesizer.

These were my guesses and prophecies.. :-)
