PlayStation 3 sales look likely to slide, according to market analysts Wedbush Morgan. It believes that the Sony super-console had its worst month at retail yet in the US. NPD figures are expected to reveal April sales of 100,000 units, down from 130,000 in March. It’s not all bad news for Sony though. Wedbush Morgan expects a continuing high level of software support for the aging PS2, with a slew of blockbuster titles due for release through 2007.
