Aye good luck to him. Everyone deserves a break from work at some point to re-calibrate.
Actually met Cliffy at a GOW2 event in Sydney some years back. Really nice bloke, down to earth and very passionate about what he does. Had a couple of beers with him and a chat about all things MS related.
I cant see him going anywhere else in a hurry. More like a long sabbatical and then back to business as usual?
