when he said "trade between" i simply took it as he MEANT from B&W1 or 2 to XY.
So with that said.. can we transfer from B&W1 or 2 to XY? or just using the app coming in December? Man... all my good stuff in in heart gold as i didnt enjoy white and never played white 2. I guess ill have to transfer to white THEN use the app to goto 3DS
