Soz m8, I don't have any info on 4.8 and only really mention it as I sign of hope to myself and others.I believe from another forum thread that work is in progress:
viewtopic.php?t=58
Going back to 4.6 shouldn't be a problem if you have eos formated your hard drive.If you have used the new fat32 format, u will have to re-format your drive for 4.6 to read it.It shouldn't be an issue, but I believe the RFX plug in structure has also changed since 4.6.
The new RFX compressor plug in is well cool, particularly if u are into break beat
Excellent for smashing up amen etc and puts sum of me analogue/outboard comps to shame.
Personally i'd be inclined to wait until a bug fixed operating system is available.However u may wish to switch back to 4.6 if u can't find work arounds to the burst noise and plan to go live sooner rather than later!
ps: the compressor plug ins will be great for live use and what sequencer are you planning to use?Have an command station lined up for the task meself,allows for drag an drop mid-files from computer, which is a real time saver
