I can confirm that I am working on VC 2.0 and that it will allow users to choose between System.Speech engine (which is what VC currently uses) and the Speech Platform SDK 11, which users can install.
Kalle has done some tests and it does look promising for bluetooth devices, but more testing will need to be done to say for sure if bluetooth will be good enough for most users.
The main advantage of the Speech Platform is that it will support many more languages, and includes some free TTS voices for many languages as well. These are not the best sounding voices necessarily, but they are free, and at least as good sounding as Anna I think.
Speech platform should also work with no training. In fact it does not allow training at all. It also does not allow for dictation, so you won't be able to use it for web searches etc.
I will be charging users a fee to upgrade from VC to VC 2.0, except for the early adopters that bought lifetime licenses, back in the early days
