Don't bet on it. Yamaha don't tend to license other's technology... they either develop it themselves or buy the company outright (e.g. Steinberg). Yamaha don't make a decent VH product as a standalone, so obviously, they have nothing they could add, at this time. This could change in the future, but I wouldn't bet on it for the T3...
