Diabolical Pitch dated, Forza 4, Raccoon City and Kinect Sports 2 DLC revealed

Among the breakout news stories from last week's embargoed Microsoft Spring Showcase — you know, the Halo 4 details, the new Fable and Forza games, and the like — was a handful of other release dates and DLC announcements.

• Diabolical Pitch, Grasshopper Manufacture's bizarre arcade pitching game, will be tossed onto Xbox Live Arcade April 4th — making it the perfect, far more entertaining substitute for the opening games of the 2012 MLB season.
• Kinect Sports: Season Two will add a new sport to its roster of Kinect-enabled activities: basketball. According to a press release, the hoops-filled DLC will launch April 4, and "[will put] players' basketball skills to the test by shooting, passing, and scoring with the new activities." We can confirm that all of that stuff is important in the sport of basketball.
• Forza Motorsport 4 will receive a long overdue infusion of Porsche autos in May. The aptly-named Porsche Expansion Pack adds 30 cars and 20 Porsche-centric events to the main campaign. No price was revealed, though Turn 10 creative director Dan Greenwalt mentioned it would cost a bit more than most of the game's other DLC.
• Resident Evil: Operation Raccoon City will have a 360-exclusive bit of DLC called "Nemesis Mode." The gametype pits two teams of four against each other, one of which hunts for an objective while the other hunts them, aided by the series' absolutely terrifying Nemesis. The pack will be available at launch on 360 for 320 Microsoft Points ($4).
