Sony Recently Announced in March at the PMA show 

Two new additions to the Sony Alpha line. These Two new Cameras are more advanced versions of the Alpha 100. One of the two cameras is called the Sony Flagship; from the tag in the glass case the camera was in we have these details about the flagship:

 Flagship model

• highest end product class A100 for professional users
• high-level total picture quality achieved by newly developed image sensor and bionz processor
• supersteady shot in-Camera stabilization
• meets the demanding performance and and specification requirements of even professional photographers

From the Images we see the Alpha Flagship Model from Sony Will have a rear control dial and a PC sync. Two of the Biggest issues I have had with the old Alpha 100. Other Features, or the lack there of, include button controls to replace half of the dial controls, no pop-up flash (we hope they will release a wireless flash adaptor since the Alpha 100 uses the flash to control wireless flash) and a small front dial that appears to control Manual or programed modes.

the other camera is for "High-Amateurs" a Camera designed to give better performance then the Alpha 100, and targeted to advanced users. 

Model for High Amateurs

• targeted to a higher level of performance then A100 for advanced users
• high-level total picture quality achieved by newly developed image sensor and bionz processor
• supersteady shot in-Camera stabilization 
• meets the demanding performance and and specification requirements for high Amateur photographers 

Both cameras were shown with attached vertical hand grips. 

Little or no information came from Sony's Alpha Product Manager Mark Weir. Weir did comment that one of the two cameras will be released by the end of the year, but no word on which one.

There is no word about the release dates or additional details about the camera. http://gizmodo.com/gadgets/sony-alpha?view=full
