A video showed up on Youku website showing us the detailed review of the unannounced BlackBerry OS 6.0.  Problem is the video is in Chinese, but you can still get a lot of information out of the video as far as the OS and hardware.

The size of the Bold Slider's screen has been the source of considerable interest, as it is touch sensitive and larger than the current-generation Bold. It sits somewhere between the current Bold 9700 and the much larger, touch-only Storm 2.

Beneath the screen is a full QWERTY keypad arranged in the traditional BlackBerry portrait manner and there is also an optical trackpad, borrowed from other contemporary Research in Motion mobiles.

Rumored to be launch on AT&T during the June/July timeframe, price still unknown, but probably around $199 with a 2 years contract.
