New DS Screens, Perhaps?

Hot off the heels of a new DS rumor, here we are with the possible new displays for the said DS Part Deux. Could it just be the larger screens that are the only upgraded feature, or will we see this make an assault on the iPhone with cellular capability? Would be interesting to see Nintendo up the ante in this department by throwing in as many goodies as possible (including the much needed graphics capability upgrade) so that Sony PSP fanboys can be silenced once and for all. Will Santa come early this year for Nintendo? Only time will tell.
