No idea, but it'd be fun to speculate.
More Amibench improvements and odds and sods of software? ARM based programming, music, office, web etc software?
Personally I'm hoping for Amiga mouse support on the DE9, an updated Amiberry, faster emulation and maybe something like a wireless mouse and keyboard to go with it.
Long term, it would be game changing to have something like AmigaLive, and play online against/with other users.
