Here's the A:NR-specific post. Anyone else notice that the next cycle is going to be the SanSan Cycle and that "System Crash" will be the new draft pool?
Rotation was inevitable, but it limits how thinly FFG can spread out new mechanics. When Spin cycle rotates out, we'll have NEXT Silver without NEXT Bronze. Stealth is also going to get a hit when the Dyson/Silencer/Lockpick trio rotate out and all you're left with is Cloak. I suppose that's one reason why the rotation interval is so long.
@karmaportrait noted that they may consider reprinting classic cards, but I think it's more likely they'll revisit themes instead of direct reprints. Once Genesis is gone, crim will need a basic in-faction decoder (probably - FFG could decide that Rex is fine for a while) and there will be some sort of meat-damage prevention because of Scorched Earth.
I'm disappointed at the planned lack of support for legacy formats. I hope the game continues to grow and becomes successful enough that it can eventually support them, and possibly a shorter format that's easier for newbies to get into. (Also: the thought of saying goodbye to Data Leak Reversal is not a pleasant one.)
The other thing that rotation gives us is a chance to farewell sets instead of chasing the newest hotness. I read a really great retrospective of H&P on BGG, and having articles looking back will be informative.
But for ultimate conspiracy value: I claim that the real reason that FFG put in rotation across all their LCGs was to cover up that it's a way to deal with Andromeda, once and for all.
