Two interesting comments from Sony:
Sony UK commented on their Facebook and Twitter page that they currently have no plans for a full frame A-mount camera:
The Sony A77 II ($948) was the last A-mount camera (announced in May 2014). There have been rumors floating around for a new A99 II model, but I have not yet seen any reliable information that is worth reporting here.
In a recent interview with AP, Kimio Maki from Sony made this comment on what would the acceptable megapixel limit be:
"It’s a very difficult question. We are the manufacturer and the demand should be decided by the customers. If the customer needs 100-million pixels, if the customer needs more than 100-million pixels, we will create such kind of a product. Right now we don’t get a strong demand from the customers for this."
