I'm sure we will see HMs again in this game. Whether we get new ones or not, I won't comment on on, but maybe we can get Rock Climb back. That would actually be cool(Sheer Force Tauros!)
I don't think there'll be another TM increase tough. 100(well, 92) is a lot already and I suspect that the increase in gen 4 was to be able to include new TM moves even with transfering from old games(as TM transfering was possible from Gen3 to 4). Now that TMs are untradeable, they are free to do whatever they want with them each generation without having to increase the number.
im kinda hoping they cut back on the number of hms. then make certain moves do out of battle actions (all "cutting" moves can cut down bushes, most fighting moves break rocks) really surf, fly, and maybe strength are the only needed out of battle moves.
