Now with something big, let us think what they could be announcing? My guess is the T-Mobile has been working on a follow-up to the T-Mobile G1 device. If there is a new device it would definitely be running Android.
They could also be announcing the launch dates of HTC Dash or the Touch Pro II, however, considering that this is "Big News" it could be something else altogether.
So what do you think does T-Mobile has up its sleeve? Are you also hunching towards another G1 like device, or are you thinking something else?
