OK, maybe a SonicCore Xite-1 could satisfy your (A) and (B) point then.
Lot's of CPU power (DSP actually), a bunch of good sounding synths, ultra low latency and a flexible rig including mixer, FX ...
But they still have to work on the VST/DAW Integration point.
Latencies issues are mainly due to sending data to the hardware and then back but this is the same as with UAD2, PowerCore, Duende or Liquid Mix.

The advantage of both Virus TI and Xite-1 is that they provide their own outputs so they can act as if they were your DAW "soundcard" outputs.

The tremendous advantage of the Virus is its well designed control surface. This is one of the main reason of the success of the first Virus I think.
I just prefer real knobs rather than mouse clicks.

On a similar level one should also check the Arturia Origin which also looks quite promising.

I also agree that VSTi being "easier" to design allows much more clever people to offer innovative synth concepts. It just allows more people to provide new concept without the need to worry about hardware ... except that they also have to deal with new OS issues
