So... it's gonna be a while then?
I've only seen pics of it in yellow. Any other colours?
Here is what the UK has available presently - white, black, or grey - http://uk.aprilia.com/en-GB/Model/72814/Tuono+V4+R/Overview.aspx
I believe they are waiting one model year until the US introduction, but that's only a guess.
