Will PlayStation Portable sport Xbox connectivity?

We know it sounds weird and that it's based on some seriously sketchy speculation, but now people are beginning to report that Sony's PlayStation Portable will be able to connect to the XBox (as well as a host of other devices). We are already aware of Sony's plans to allow games to be continued on the handheld device and vice-versa, but if they come up with a way to allow developers to do that on multiple platforms, well, we'd be really impressed (and really, really surprised). As for what other purposes this could serve, we can think of some GBA-like features for party gaming, map and crucial data display, as well as transportation of game saves. Weirder things have happened, but we're officially taking a skeptical stance on this one.
