If Guy had been involved in it, for sure it would have said on the MKNews site. I mean, he's not that special. But I'm curious about who the lead singer and guitarist will be. Theoretically, it could be Mark, but if he was into it and they really wanted to raise some serious money, he would have been involved in the whole project and they would have called it "Dire Straits reunites for one night only". Not just "three former members (one a bit, one not really) invite you to a jolly trip down the Dire Straits memory lane". But - never say never.
