Well, V281 successor technically exists so naturally there will also be a dedicated amp. I don't know when and I am still guessing autum. However autumn is near and we have no confirmation. We're in the middle of the holidays now in Bavaria so news will be very slow.
If you're from the US I'd really think about the ongoing deal with grabbing the reed relais for the same price as the RK27 version. A standalone V5XX with reed relais is now very close prise-wise. Might as well grab a great DAC along with it too.
However I understand if people want to have one DAC only or want a "pure" amp.
Edit: ok, you're from Russia, so forget about the deal.
