I had to make the same decision some weeks ago, and I've got a Virus B at the end, compared it to the C and the Snow, also checked the TI. I would recommend the C, which is very similar to the B. The newer models have got some more features, voices etc, but are totally overpriced and, soundwise, not that much better than their predecessors. The original and sexy Virus-sound can be achieved very well with B or C.
Also the 'Total Integration' thing on the Snow seems to bring more trouble than fun. Many people spend their time fixing problems rather than creating good sound. So if I were you, I would get a C and wait another two years to consider the Snow or TI again.
I prefer to get a bit older models in good shape, which were top notch a few years ago, for a fraction of the money you have to spend for brandnew gear. Musically you won't get much advantages with the Snow or TI anyway. I can see that on the Virus B already: for me it's neither necessary nor possible to use ALL features the B delivers to create some really tasteful sound.
By the way, for me the process of making music gets more complicated and slower, the more features and possibilities I have at hand. For me the B and C models are the perfect balance between functionality and simplicity, with no compromises soundwise. Ok, I have to admit, that I have a Roland V-Synth already (for Hypersaw and such), which is a monster, but apart from that the very special character of the Virus stands for it's own, and I could do it without the V-Synth.

Good look, and have fun
