i think it's too late now, the game is finish, no possible to catch and rewind the time.
The last chance for Pentax is create this FF for this Photokina (2012), bref, same the others Nikon (D600 & Canon 6D) and same sony with his little rx1 and others models.
All users want buy one FF is out, it's look D600 and 6D.
I think if Pentax built one FF for 2014, it's again a bigger error, the users are already switched to FF, and think's go switched.
The train is running, pentax has look this train running and ptx nothing built, too late now, time is never return backward ! if... the movie with this name
