I just went to my local CanadaComputers joint here in London, Ontario to place a deposit for one of those 22nm bad boys and lo and behold those mofos already had the 3770Ks in stock.
Apparently, they already received them two days ago. Legally however they are NOT allowed to advertise till the 29th. But you are more than welcome to come in and grab them before the official release.
So there you have it. Go see if your local retailers have them they aren't just saying anything.
P.S. I paid 369.99 CDN for mine. Kinda steep but my Sabertooth Z77 is collecting dust so I figured I might as well get it. Now it's just a waiting game for Corsair to release the RED Vengeance 2400MHz kits and or anything better that compares to the DDR3-2800MHz G.Skill Trident X kits (which all the Trident X have been recalled from what the store clerk told me?)
