My guess would be that new 8 will be similar to the 2005-2009 level 8 that someone mentioned up thread, except instead of C skills just being allowed, 1 will be a requirement. I think vault will be essentially the same as current 8, with a flipping vault being the norm. Bars will probably be similar to how it is now, but add in a harder dismount/extra circling skill to hs and I would think that maybe low to high and/or high to low releases will become more common at level 8 (toe shoot to high bar, overshoot from hb to lb). Beam will see level 8s once again doing back tucks, though there will be other options I would imagine. If you can find level 8 routines from around 2009 on youtube you might be able to get a general idea, though that is just speculation on my part.
