In an attempt at realism (or as a way to bring up skintight-bodysuit-wearing Jeri Ryan) Star Trek Online has posted an "interview" with Seven of Nine that hints at a Borg threat in the game.
The fictitious encounter between the interviewer and Seven of Nine covers plot points about the ex-Borgette leaving Starfleet to work at something called the Daystrom Institute. It also shuts the door to any Chakotay/Seven of Nine romantic subplot.
But the "point" of this little marketing exercise seems to be announcing the Borg in Star Trek Online:
Interviewer: When do you think we'll see the Borg again?
Seven of Nine: I cannot predict when, only that it will happen.
Jeez, I guess turning human made her into Donald Rumsfeld.
