I'm also very much looking forward for this... and crossing my fingers the upgrade won't be expensive 

It may be soon to ask but if I upgrades to MIR 3D can I switch between it and pro(24) for different projects?

Also, in contrast I've been eyeing Spat revolution essentials and I'm wondering in terms of virtual space will MIR 3D also offer some kind of "neutral" space without much of a room\venue feel to it?
