Sony and one of its sister-companies, Sony-Ericsson, are hinting at a couple of interesting possibilities for a PSP phone, including the possible addition of VoIP capabilities to our favorite handheld as well as the potential for Sony to introduce some sort of brand-new "Playstation Phone" Frankenstein that would be separate from the PSP all together.

In an informative and fun read, GameDaily goes sluething and digs up some interesting evidence that supports the rumors. Here's our favorite nugget-of-fun:

"Sony Ericsson's senior vice president of Product and Application Planning, Rikko Sakaguchi, said such a phone may actually be in the works. Sakaguchi cryptically revealed to CNET Asia that the company 'is working on something' related to a PlayStation phone, but that 'the surprise must be kept for the future.'"

Without doubt, that quote is cryptic, non-specific and bordering on hearsay. But that's the stuff that fanboys like us live for. Now, go and discuss.
