I am eargerly waiting for my vArranger USB key to arrive. I like the flexibily to be able to drive it from all my midi controllers -a tiny midi keyboard controller like the Akai LPK25, an 88 key, or the FR7x digital accordion. I am also excited about making more use out of my VST plug-ins and some good soundfonts from my Live-Styler sound libraries let alone tons of styles for Yamaha, Ketron, Korg, and Roland.
