I think that RC2 will do just fine at 256kbps. The only major issue at
this bitrate is pre-echo, but you will hear pre-echo very rarely IMO
(especially if you don't have some artifact-listening experience!).
IMO, RC2 is higher quality then beta4 at 256kbps - there are no bass
tunning bugs and some subtle high-frequency bugs are also gone.
I have started using RC2 for archiving at 256kbps since RC2 fixed most
problems with some of my test clips.
Even if you do come across some artifact, it won't be something that
will "jump in your face".
The trouble with lossy compression is that you can NEVER be certain
that there will be no artifact (bitrate independent). Lossless
compression is the only way to be sure everything will be OK.

No one knows when RC3 will be ready, not even Monty (the boss). Also I
think most of time for RC3 will still be spent on improving lower bitrates
because that's what most people use, so there are no guaranties RC3
will fix every known test case.
So if you are planning to use 256kbps mode then I really don't see
much point in waiting. If you want to use lower bitrates, then I would
suggest you wait for RC3...
