In an interview with EPhotozine Panasonic talk X lenses (as first exclusively revealed by EOSHD last week) and the GH2.
Mr Uetmasu product developer:
A firmware update may be coming for the GH2 to add support for 25p, and additional improvements in video abilities. If there are features you want adding, contact Panasonic and let them know. They are aware of the work the “hackers” are doing and are impressed with their work, but that they (Panasonic) need to test everything / confirm there are no problems before rolling out updates. The GH3 is not due imminently, as the GH2 is still extremely popular, but that there is a high end GF series camera in the works.
Will be interesting to see what the ‘other’ video improvements are! Hopefully AF tracking and 60p.
