If it is supposed to change “everything” one would think Steinberg is referring to something a little more general than a specific platform event or app. Perhaps they are introducing a new fresh protocol, e.g. like mLAN or equivalent, since VST2 development has ended, that’ll marry VST3, MIDI, Audio, Video, Cubase, HALion and hardware, etc. together? 
Of course, it could be more specific… maybe Cubasis for Windows 8, or it may just be Cubase 7.5 or HALion 6? 
Hmmm… what they think would change everything is possibly very different than what we would consider as such.
USB eLicenser alterations? An optional online eLicenser, multiple instances across two or more concurrent computers? Steinberg software for rent? A new instrument or another awesome synthesis engine perhaps? The Crusade Revisited, the choral plugin? Direct audio feed into NSA servers?
Hype sounds very good, and it could be anything, but I sincerely do hope that everything changes on November 14…
…if it’s BETTER for US!
How about inputs (i.e. as side chaining for VST effects) for VST instruments?
