I don't see this game going on any significant sale as it's already being sold pretty quick, you can see all the regional pricing here: https://steamdb.info/app/671860/

This game will probably stick around for a bit, so if you haven't bought it yet, might be a good idea while it's still in early access before a slight price increase. The gameplay is very similar to earlier battlefield games, perhaps a little more hectic with more players.
I read that the only reason why it has remastered in title is because development of the game had restarted multiple times, there is no original BattleBit game this is the only one.
