An ad for NIS America's upcoming (awesome) DS ports of Disgaea and Rhapsody prominently features an image of a DS with unusually wide screens. Now, the ad itself is obviously Photoshopped, but has NIS accidentally leaked something we're not supposed to know about until Nintendo's press conference next week?
The odds seem about 50/50. Nintendo has already denied this DS rumor, of course, and it's possible NIS just wanted bigger screens to cram their art into. On the other hand, the DS Lite is at the three-year mark in its lifespan. We're about due for a new hardware revision of some kind, and "DS but with widescreen" would certainly fit Nintendo's revision M.O.
We'll know for sure after the Nintendo Press Conference next week (which omgNintendo will not-quite-live blog), but hey, that leaves us a whole week to monger delicious rumors in the meantime.
