Haven't seen any pre-order prices for these yet. Catalog price is just under $1,300. Realistically I would not expect them to sell for less than between $1,000 and $1,100 and probably more towards the top of that range. It's a whole lot of engine with a proven feature set and detail. The three units as a whole measure 4.50 feet long.
P.S. Previous issues of the UP80 (I have two) retailed for less than $1,000. I think that this issue will break that barrier. Also BEWARE that although MTH has the tooling for all three units in the set, I waited two years for them to produce my PS2 version! That's BTO MTH style.
