According to an article recently posted on Serebii the Pokemon gen 4 remakes have reverted to single use TM's and retains the forced experience share and ability to move Pokemon between your party and storage from any place. Personally I think that you should have the option for either a modern or classic mode as well as difficulty options and you get a virtual award if you complete the game on classic mode and or a higher difficulty.
