Apparently everybody was paying taxes last month instead of buying games, because despite analysts' expectations, sales for April were way down. As you can see below, sales dropped out on every single console that NPD tracked during April, with the Wii taking the biggest hit, down 50 percent from March. Hardware sales overall fell by 37 percent.

Software sales didn't do any better -- Splinter Cell Conviction was a bright spot and Super Street Fighter IV just barely made the list (which you can find after the break), but otherwise it was all leftovers from March and previous months. NPD reports that last month's 11 percent industry drop-off was the "worst year-over-year decline...since July '09, and the fourth largest year-over-year percentage decline ever." The industry got rained on -- here's hoping April showers bring some May flowers.
