The March report from the NPD Group is out, offering the latest guestimates from this trade group on video game hardware and software sales. GameSpot has a summary of the results, showing the now-expected year-over-year 10% slide, which is accompanied by the now-expected disclaimers of how their methodology may not be keeping up with the rapid pace of the transition to digital distribution. Here's word from NPD Group analyst Liam Callahan: ""When you consider our preliminary estimate for other physical format sales in March such as used and rentals at $190 million, and our estimate for digital format sales including full game and add-on content downloads including microtransactions, subscriptions, mobile apps, and the consumer spend on social network games at $670 million, we would estimate the total consumer spend in March to be just under $1.9 billion." That said, after talking of "deep declines" of lame duck console hardware, they actually report an uptick in software sales, saying they were up two percent in March 2013 across consoles, portables, and PC, called "the first month of positive growth since November 2011." They also list the top 10 selling games for the month:

1. BioShock Infinite (X360, PS3, PC) - Take-Two Interactive
2. Tomb Raider (X360, PS3) - Square Enix
3. Gears of War: Judgment (X360) - Microsoft
