I do agree that there is a kind of "vibe" in the air of potential change in the line, though I don't really feel like it will be a huge shakeup. Generations as a whole has some momentum right now, with the mainline, Studio Series 86, the Haslabs, comic series, and various store exclusives. TBF though, we are seeing a lot more older figures getting reissued, and we're down to 3 waves a year (less of a blow due to all the other avenues mentioned earlier).
Also, despite getting so many great obscure characters over the last few years, there are still seems to be certain eras that I worry we may never get figures of. Shell-feature Pretenders (for those that need them to be such), Euro G1 (we got Rotorstorm, and a base mold of Skyquake), the new mold G2 characters, Beast Machines (at least give us new molds of the 3 main Vehicons please), Energon (seems to have been skipped over for Armada & some Cybertron, but maybe they'll move onto it). I have faith that the Transmetals will eventually get something, if they can accept metallic paint instead of chrome. Victory was on this list until a few years ago, they've done a great job at making those characters. The Omnibots & Throttlebots could use full releases too, they're just cars. Hasbro loves making cars. I'm sure others here are holding torches for other characters, too.
