I do hope that, once they finish these "extra levels" (because really, we can't stop them anymore with that, they've already made the first step), they finally lay this game to rest, with an impressive final boss and "end game" we always wanted.

Then they work on PvZ3 or the like, and let that have upgrading, but in a more "worth it" way and from the start, so the game is built around it, not just a few levels added pretty much last minute.
