You are 100% right about the Flash oversight. Hopefully they will serve both crowds by releasing the Retro Flash at/about the same time as CS Sci-Fi.
As for the big vehicles, yeah, besides the obvious large investment, the size was a significant hinderance for me as well. While I liked them both (particularly the Rattler), I knew that I would ultimately have to supplant one of my hanging 1:18 vehicles for each Haslab aircraft I'd purchase, because I have nowhere else to put them and could never leave those in their boxes. The idea of turning what is a pretty consistent (and a bit more grown up) ceiling display into a hodgepodge of 12 & 18 scale real world and fictional vehicles ultimately didn't really appeal to me.
I'd been down the its-way-too-big road many years ago with 1:6 scale vehicles, which together literally took up a bedroom (floor and ceiling) in our first townhouse. I came across some good deals and got way too many of those figs and YUGE vehicles. They ultimately ended up in storage rooms and attics when our kids began to come along and stayed stored at our next two houses before ultimately the figs and some of the smaller vehicles were sold off and the larger ones got taken to the landfill.
I feel like I could maybe do a Vamp MK II and a Stinger, but they would be the absolute largest vehicles I could find a place for (I say that until they drop a proper Snow Cat or a MOBAT
). And, even those would require me to clean out the one cluttered corner of my office and likely dispose of a legacy entertainment center in exchange for something better suited to display them on.
Will I ever go large? That'll likely come down to what Hasbro produces and how good it actually is. So far, I've been able to resist all by the cool but very manageable RAM v.3.
