According to the WSJ's China Real Time Report, Dell's Amit Midha, president for Greater China and South Asia, said the company is hoping to release the Streak in China. Dell's Mini 3i smartphone is already available there (it was released in China before anywhere else), so the Streak will have an Android relative to hang with if the launch plans move forward.
Not even a vague timeframe was given for when the device could be released in China, but I'd say it's safe to assume that it will be after the device hits the states. Whenever that is!
