If you are completely set on a low mass turntable and know that's what you prefer, then by all means wait for the new Regas. However, the new Regas will be no different from the old Regas, in that they will have the exact same philosophy and likely the exact same performance.
That being the case, in my opinion you will never realise the full potential of a top-of-the-line low-compliance cartridge on a Rega set-up.
If I was in your position, with a comparable budget, I would first get a phono stage, then a new arm/turntable and only then begin thinking about a cartridge upgrade. The way you're doing it now seems awfully backwards if an optimal result is what you're after and can only unnecessarily complicate the process.
Again, in my subjective opinion.
