Regarding the coneheads, we're in an era where the previous seeker mold just got 7 uses in one year, including the first transforming figures for Ion Storm and Nova Storm, and the first ever figure for Red Wing. And besides the deluxe Insections, Omnibots, and Bumper if you count him, I think they might be the only bots left from the '84-'85 era that haven't gotten any updates in T30/PWT/WfC. If this isn't the time to get a new set of coneheads, I don't know that there ever will be such a time. I'd be shocked if they don't get new figures before WfC is over.
Aside from the main six, I'd love to get a welcoming committee set at some point between Earthrise and the third line. A year ago, I never would have even put enough credence toward that idea to put it on my personal TF wishlist. But we're living in a post-Rainmaker/Red Wing world. Instead of wondering whether it's even possible, I'm instead debating the merits of whether they should use the Earthrise mold that's likely to become the new seeker standard, or the Siege mold that would seem to be more appropriate for them.
Aside from seekers, we still haven't seen anything about a WfC Frenzy or Buzzsaw yet, right? What do you suppose the odds are that they're being held back to release alongside an Earthrise Soundwave? Now even boxier... somehow.
