According to some site we didn't know at all until now, the PS3 Wii-style motion sensing remote is not only not a rumour but a done deal. It's already finished, they say:
Sony is reaching out to key third-party publishers and asking them to implement last minute functionality into their soon-to-be released games and of course compatibility with select future games.
We don't know if it's true or not (heck, I don't even know if it makes any sense at all for Sony to release a Wiimote, although it's entirely possible they would, given Nintendo's success). They don't provide any details, however, so remember our first rule of rumors: Fried them until they are golden brown before serving along some veggies and red pepper sauce. Or don't trust them. I keep confusing this one. [Kombo]
