I think we will see some big announcements not only for HP, but also from 3D systems and Stratasys, as they try and keep up with HP.

On top of this, I think we could see something from Cubify, and Ultimaker. I doubt we will see anything from MakerBot before the end of the year. The 5th Gen stuff seems to be getting pushed pretty hard, and all of the 5th gen printers aren't even available yet.
