The Singapore gathering appears to focus on entertainment but has been linked to the smartphone, which may also appear at the same time as a Bluetooth headset based on FCC data. The possibility exists for other phones but hasn't been supported by other rumors.
If the Xperia X2 is indeed announced at this event, the next big question will be: How quickly will it come to market. The X1 took its sweet time and never picked up carrier support in the United States. It'd be real shame if the X2 suffered the same fate, given that it reportedly will sport a 3.5-inch OLED touchscreen and some better processing power than its predecessor.
