Toshiba quitting the Pocket PC business?

This rumor has been trotted out before, but the word on the street is that Toshiba is getting ready to exit the Pocket PC market by the end of the year. This comes just weeks after Sony announced they were halting production of their line of Clie handhelds everywhere outside of Japan. If Toshiba quits it'll leave just palmOne and HP as pretty much the only major players left making PDAs.
