If anybody is interested, I have a Google Sheet (link below) by which I'm tracking participants in the Conversion Kit Exchange I've organized for the SF Bay Area. As a side effect of tracking the participants' purchases, shortfalls, and extras, I'm getting a pretty good shape of where the demand is going to fall very short ... and, as an aside, where FFG did not do a good job (though I make no judgments as to how purposeful the disparity is, in terms of driving sales).
The thing I find most interesting so far is the entry for StarVipers. They are running a sizable deficit, whereas the deficit for other ships, both Rebel and Imperial, is all the early, extremely iconic ships. FFG really did a good job with Guns for Hire making StarVipers worth flying and in-demand.
They did a terrible job estimating demand (if they even tried) with Decimators, Lambdas, Gunboats, U-wings, Rebel TIEs, and the Sheathipede. So far it's looking like it's going to be tough to literally give those individual kits away. TIE fighter kits, in particular, are going to be highly in demand.
I really wish they'd simply polled 100 players, collected the data I'm seeing, and build the CKs' contents based on it. I still think the CKs are a very good deal, but it's easy to see when looking at things why some people are angry about the distribution. It could have been much, much better.
