i saw the other day that lotus announced that they have signed an experienced driver but won't release who yet as they'd like to anounce both drivers together. given that some of their senior personal are big trulli fans it looks like a safe bet it's him
but I doubt it'll happen~
I'd love to see Rosberg paired up with another Japanese. Nakajima has shown himself to be of lower quality, so chuck Kamikaze into the mix!
