Give me a schedule of when different game modes are coming!

I'm so sick of not knowing when RUSH modes are! I only really like rush because sometimes I hate waiting 2 days for my slow units to get to where I want them. Usually, I can play x4 games in real time, never having to leave.

Anyway, is there some schedule of when the next Rush mode is or can you guys just make one of all the upcoming game modes and stop this random crap? Thanks.
