That might get unwieldy pretty quickly.
Would a "new battletech product for sale" thread stickied in General Discussion be easier to maintain? (Plus then I can subscribe to one thread instead of a few dozen sticky product announcements.) Just a thought.
The real answer, frankly, is to release products evenly throughout the year, and not have
four clumped up all at once.
Because if things were being released one at a time, then yes, I would have just split this thread into "New Releases" (stuff that's actually out) and "Upcoming Releases" (speculative or announced-but-not-released-yet stuff.)
But with four major releases coming out all at once (six if you count each novella and each box as one thing), the cross-talk on a solo "New Releases" thread would be unbearable. It would just inspire people to spin off separate threads for each release anyway--we already saw one for Shattered Fortress, for example.
This way may not be great, either, but it might be slightly less maddening for someone who's interested in talk about, say, the box sets, but not about the novellas.
