Well the TE round 2 stick is the same as the first batch, so there's no difference really. There's only been 3 truly different TE sticks, as far as I know: TE, MvC2 (different button placement), and the TE-S (new PCB and a different body?). I was hoping for a completely new design for MvC3...
My current TE is a little beat up, so I want to order some seimitsu parts for it and order a new TE for the sanwa. meh
