Of the PS3's motion controller, the alleged Sega document says (and remember, this is neither confirmed, nor from Sony):
Motion Controller • Spring 2010 launch (March in JP) • No bundle/pricing details yet, should come Sept 1 • Plan on selling 4-5MM units WW • SCEA agreed to provide a list of Sega IP that would work well with the motion controller, Virtua Tennis was an example • Motion Controller support allows easy way to differentiate PS3 SKU • Other differentiation opportunities include PSP/PS3 interoperability – think of features that would make users want to buy both PS3 and PSP SKUs.
Spring 2010, we knew, but March 2010 in Japan is the first time a date has been attached to the peripheral. It's also the first time we've seen an actual game linked with the device (though again, it's important to remember that this document is neither confirmed, nor an official plan of attack from Sony).
Interestingly, the document also contains mention of a PlayStation Network "import store". Once again, remember, this is just Sega and Sony talking business, so this may not happen.
But enogh disclaimers! The document says Sega "could put Japanese games directly on PSN for download in a special Japanese Import section (pricing $US9.99 to $US39.99 for full game)". Specific mention is made of the Yakuza series, and how Sega "might need to localize menus at least with subtitles".
Discussions and rumours or not, that would be an exciting prospect for a lot of people round these parts.
At time of writing, we're still yet to hear from Sega or Sony on the matter.
