Oh, no -- we're not done yet: The Hydro Thunder Hurricane Tempest Pack DLC is also coming out this Wednesday ... Okay, we're done now.
Update: Microsoft's Graeme Boyd (a.k.a. AceyBongos) has tweeted that both Bloody Good Time and Haunted House are not confirmed for release this week. Of course, Boyd's wording indicates that both releases could still happen.
Update 2: Wednesday has arrived and, sure enough, only 3D Ultra MiniGolf Adventures 2 and Pinball FX2 have been released.
Update 3: Okay, last one, we promise. Bloody Good Time and Haunted House have now been released. A day late.
