Lets hope that the pricing stays reasonable. The MTX-3 started out around $350 retail at my LHS when it first came out. If the MTX-4 is under $400 starting, I may not wait and get one when it hits the shelves of my LHS. Wished that its release wasn't so close to the Paris race. I would like to have one in hand to run at that race but should do fine with the MTX-3.
