Can we expect to see Ultra Rapid Fire on PBE?

Since it seems like Riot is planning on testing the majority of modes planned for the new Rotating Queue (I could be wrong, but we've already been able to sample 2 modes in the last few weeks) Can we expect to get Ultra Rapid Fire at some point? With that; Will we see every mode that is planned to be added? Or will we just see a couple as a test, and then the full mode will be launched? Cheers!
