Money wise and for profit purposes I doubt KORG would include most of what you suggest especially a 88 key version when they already have a 76....they are concerned about the mass user and how profit can be made with just enough inside to bait the buyer to wet his appetite so they will yearn to buy the next Pa6x, Pa7x or something else totally new, etc,...it's all about making money....but anyway keep dreaming...I'd say since Styles dominate arranger kbs Don mason hit it right on the head to improve their style quality meaning endings,fills, quirks, etc, first.
