Here's the no-brainer rumor of the day: Rare will release a sequel to its million-selling shooter Perfect Dark Zero. The Rumor Mole section of the May 2007 issue of Official Xbox Magazine reports that the sequel was revealed "by way of a press release announcing the next novel in the paperback series that also mentions a follow-up to the game."

We haven't been able to locate the press release ourselves, but the paperback series is an official tie-in to the series. If a sequel does come to fruition, we wouldn't be surprised. In fact, we've heard it from an official, anonymous, trustworthy source that Rare has been deep in the early development phases (pre-pre-alpha, if you will) just trying to figure out the best numerical nomenclature. Perfect Dark One is off limits, PD Zero Two is pretty meh, PD Negative One (shortened to PDNO or PD-1) could work for yet another prequel, or perhaps they'll go the Lion King route and make it Perfect Dark Zero (point) Five, or PD.5 for short.

Still, we side with our Fanboy brethren: the Xbox 360 has enough shooters, Rare should focus on meeting their sequel quota with a return to platformer Kameo.
