File this under "Rumor" for now, but the folks at Clipset are reporting that Sony is looking for some cellphone gaming action via their Sony Ericsson line of mobiles.

Like the high-end Cybershot and Walkman phones, Sony Ericsson's new "gaming" phones would pack a lot of media muscle and have an interface like the PSP's. The idea sounds feasible, but considering Nokia's success (or lack thereof) with the N-Gage and Sony's own success with the PSP, we're not quite sold on this just yet.
