HTC Already said they will roll out for the DInc. It's just a matter of VZW testing how much bloat they can jam in and still have the thing boot!
And by the time they have finished testing and installing all the bloatwere they can we'll probably be talking about Ice Cream Sandwich. Oh well. I'm already running Gingerbread thanks to Cyanogenmod so I'm really not worried about the official update anymore.
Remember guys that our DInc was one of the first to get Froyo. HTC is great about putting out updates and I wouldn't be surprised to learn that VZW has a build already. They will do their extensive testing but I am sure we will get it. Blackmanx has said he was confident it would.
