I, personally, look forward to the RP2 pumps making a comeback. They're the only thing I've found that could not only suck up fluids, but also eject them without needing a special kind of pipe; all you had to do was run a grate on the reverse end. If nothing else, it was great for making pools. That, and I just liked how they worked and operated when compared to their BC counterparts. No, I didn't mention IC2 because nobody uses IC2 pumps.
