The basis for this guess comes from the fact that Amazon.com has put up a pre-order for Star Trek Online. And guess what? They’ve got a date attached: February 2, 2010. And given that we already know that the game will be released in Q1 2010, this could possibly be a correct date.
Should we lock in that date for the release? Not necessarily. As no official release date has been given by Cryptic, it’s possible that that date is only a temporary one while Amazon (and the rest of us) waits to hear an official one given from Cryptic.
On a side note, do consider pre-ordering the game. The perks, as listed on Amazon.com, aren’t too bad: access to open beta and a special bridge officer for your character. Seems like a nice little addition to having the game reserved for you. Oh, and the 6% savings you get for pre-ordering right now, too, is nice.
