Yeah, that's what I'm debating, too: Is Scoutie the last of the old or the first of the new?
On the "last of the old" side, he's using the old Prometheus body, so that's sort no beuno.
On the "new" side, the timing feels right for it to be post-new-Disney-contract,
it is a $40.00 price jump over the Snowtrooper (as Luke is to Hoth Luke), and IMO a new level of weathering detail from SSC (just compare it to the god awful Sharpie-weathering on the Clones). In regards to the bike component, hard to say. I think the $300.00 price point is in line with the e.Web, Dewback and Tauntaun, but still expensive enough to make a tidy profit at full MSRP, even with Disney's adjusted cut.
My speculation is it is Luke's sculpt and paint that is driving the price so high on him. They'd either have to tighten things up significantly in their existing factories, move facilities or maybe sublet from HT. At least if it comes out looking like the prototype, we will know SSC made big changes that likely were very expensive. If it comes out distorted, like Drake or the Clone portraits, then we'll really be scratching our heads in regards to the price jump.
That's my reasoning. The price speculation is probably silly, but it's fun, all the same.
