When will we be seeing the 2047 pipe/engine combo being sold in the U.S.,or is it already being sold..I also read that the 5 port/7 port have a little more work done to the engine and also come with more stamping on the head.

I really want to pick one of these up but would perfer to wait untill they reach the U.S.
