Alright, seeing as this isn't a new game but still a fourth generation version of Gold and Silver, I wouldn't expect any new moves to be introduced other than that from what was brought in during RSE, FRLG, and DPPt. Like stated before me, new moves will be brought into the games when a new generation comes out, because seeing as DPPt has no collected data on any new moves, compatability wouldn't work between the remakes and DPPt and HGSS if it had completely new moves.
Also, when FRLG introduced Blast Burn, Frenzy Plant, and Hydro Cannon it was only because RSE had already had this built into the game. The only thing was that the moves were never needed at the moment, or were just a side idea that was never implemented at the time. This is how it worked easily between transaction with RSE and FRLG. Though, I don't see any need for new moves like this, until the next generation.
However, if anything were to be altered, it might just be accuracy, like what was done in Platinum. For example, accuracy from Hypnosis in Diamond and Pearl was 70, but in Platinum it was brought back down to 60. So, other than this slight change or a few minor adjustements in move pools for a Pokémon I wouldn't expect anything new dealing with moves until the new region games are brought out within the next few years.
