Adobe have had a financial meeting and it appear Acrobat 10 will turn up sometime in the fourth quarter. But why? What features? Sometimes I think the Adobe view is that the PDF upgrade income is automatic. They only need to promote Flash for the future.

A Google search can only find comment on the previous meeting in June.

Shantanu Narayen:

Mike, what we are seeing is a lot of Acrobat usage right now within enterprises to do what we call critical document workflows. The integration of Acrobat and acrobat.comis ripe area of innovation and opportunity for us to continue to deliver value to customers. Delivery of PDF files across mobile devices is becoming an increasing use case for us. So, multiple innovations are on the drawing board and we are excited about the new version that as we said will come out later this year.

Maybe something will turn up. Apparently the fourth quarter ends in November. So perhaps Adobe will release some info eventually.
