I only see some blogs mentioning February announcement w/ release right after, but I don't see that on all the blogs (just a select few).
I think it'll be a year from when the Note 2 released, quite honestly. I think all the talk about the Note 8 tablet has confused bloggers into writing about the Note 3 (even though there have been no FCC leaks, bluetooth certification or wifi certification leaks). And since they started writing about the Note 3, they probably figured that people are clicking through, so why not keep speculating until the time has passed, just to get the traffic.
