Great news but I expect i'll hold fire for a wireless Model D, I currently use a wired one and it's really nice to use, almost as good as my all time favourite, the Habu.
I also noticed that Razer have a wireless Deathadder launching, that would be my third best mouse but the £130+ price tag really puts me off, especially as that doesn't even come with the swanky charge dock like the Viper wireless has. I think the Glorious D Wireless will be cheaper, lighter, and probably perform just as well, so i'm going to hold fire for now.
