Something tells me LG did not intend to announce an upgrade for the myTouch Q. It was the only phone tied to a US carrier that was mentioned in the post, and I find weird they'll update the myTouch Q and not update the touchscreen-only version of the same phone.
The cat's out of the bag now so they better upgrade the myTouch Q or we'll hold that against them, and everyone knows LG doesn't need any more bad publicity because of failed updates..
