Motorola Q

It seems like Motorola waited so long to finally put out the Q that it already has competition on the way. This new phone by Samsung looks hot and it's in black with buttons that look comfortable to use.

Does anyone have any more information about this phone? Carrier, etc.? It's a GSM phone so I'm guessing T-Mobile and it's supposedly coming out this month but I thought the new Sidekick was coming out this month too. Can anyone confirm? And does anyone think this phone can really turn out to be the Q killer?
