This is a friendly reminder that the BioShock launch trailer will premiere tonight on Spike TV. It will premiere during the 9pm hour, during the show The Kill Point. Plus, right after the premiere, Geoff Keighley will have a surprise announcement. Geoff tells me that all the Bioshock goodness will hit around 9:45pm ET (and then at 9:45p PT for west coasters.)
Expect the HD version to appear on the Xbox LIVE Marketplace shortly thereafter.
