//-128 voices polyphony (at least)//

Roland can do that.they already have it in the Xv line.

//-Sequencer quality of XP80 at least//

I thought the best thing they did was to take the MC-80 and stick it in the fantom.

//-an EFX processor for EVERY TRACK on the sequencer//

Not going to happen. The only keyboard that was close to yoru request was your old school korg Trinity.(I don't think it's old school but lot's of people do).8 insert Efx.

//-a decent sampler//

Roland will probably take the VP-9000's features and stick it in there next big thing if they will ever do it.

//-LOTS of expandability//

I sure would love to see 4 SRX and 4JV expansions built in like the Xv-5080.

//-floppy and Smartmedia//

Roland will probably use MINI-CD if they are smart enought.MINI-cd have 210MB and way cheap than a smart media and comes in two types. MINI-CD-R and MINI-CD-RW.

just my opininon.
