Sonyalpha.es was able to get a better translation of the DCWatch link (posted here last week):
"Toru Katsumoto, general director of the division of Sony Alpha SLR cameras, has confirmed in an interview with DC Watch that will substitute for the A700: "... the product might be called the A700's replacement will appear sooner or later." but can not confirm when, because "when you think like a project can not promise that will appear next year.".
It also implies that there have been changes in the initial idea for "the control of development trends while following the road map is always complicated," which might suggest that they were surprised something (perhaps the video?) On full development and had to change their plans, something that is possible for the delay in the appearance of a substitute."
