The Virus TI2 is a very powerful hardware, it has great potential to grow and mutate further.
One idea would be, for example, say you have your multi mode, with those 16 parts, each with its own stuff. And in integration with Cubase or any other DAW that you use, being able to make stuff for each of the 16 parts, each one of course has its own FXs.
But what if, say, we'd have the ability to chain FX? That is, in the simplest vision, route the signal of the preceding part to the input of the next part (similar idea to what the Elektron Octatrack does with its different type of 'Machines'). So, for sound design aspect, the user would be able to create a 'patch', with say part 1, but take advantage of the power of the Virus TI, use the FX blocks, and then use more FX blocks from other parts, making it like a multi-FX unit of some sort. I don't know how that would be implemented without messing up the known work flow of the Virus. So for example, you want to use Reverb, then put through Delay, then put through Distortion, then perhaps Bit Reduction, then maybe split the signal, and mess with further FXs. So typically in any DAW - Cubase, FL Studio, Propellerhead's Reason, you can do that, route FX in a complex way to create new interesting energy for a sound. Or for hardware FX unit, Lexicon MX400 can do something like that.
An alternative work-around for that would be using a sampler like Elektron Octatrack, or using any of the DAW i mentioned above (or hardware FX unit), or NI Guitar Rig 5 (for guitarists, etc). But the Virus could, at least in theory, given the specs - be able to do this kind of thing. So maybe in some future OS update, this kind of idea, would be awesome to consider. Imagine having even just one 'sound' or 'patch' with accessible FX parts from each 16 parts? plus parallel and/or serial routing, the Virus would be virtually unbeatable!
