Yeah, that first question is awkward, I know. I was trying to get this up before someone else did! Anyway, of course I want new TMs, and I really hope they're reusable like in gen V. It didn't make sense for them to break in previous gens. I assumed you pressed it against the Pokemon's head to make it learn a TM and that's why it broke. Not anymore!
As for old TMs that should make a comeback in gen VI, let's have elemental punches, Dark Pulse, Roost, Stealth Rock, and Body Slam. Going old school with that last one, haha.
