EA finally gets the Wii, and not in a way that will excite hardcore gamers. Ghostbusters goes missing. PSP jumps. And more observations you can use at cocktail parties from today's June NPDs.

A fighting game blow-out. An EA surprise. As always, some notable omissions. And an NPD-PD PlayStation bump! For your May NPD gaming sales armchair analysis, consider the following:

First month Grand Theft Auto: Chinatown Wars did not impress. At least they weren't impressive to analysts, as the game's initial NPD figures came in far below expectations. What about month two?

The experiment continues. In a quest to give people apples-to-apples sales comparisons, here are the Kotaku-coined NPD-PDs for April. That's NPDs "per day."

For those who love arguing about gaming sales stats, we hope we've devised a way for you to argue better.
