Are they really doing 5, 6 and 7?
If they are that probably doesnt bode well for DS9-R. Unless they are planning for a longer gap between the release of TNG-R season 7 and season 1 of DS9-R?
Yes. Thankfully CBS Digital are now streamlined enough that they feel they can manage the final three seasons.
DS9 has not been green lit, so we really shouldn't make any assumptions.
...So when you figure the remastering work on Season 4 is all but done now thanks to Modern Video's help, CBS-D has surely already moved on to Season 5, and then when that's done they have the luxury of doing only two more seasons throughout the entire year of 2014. So for example if the higher-ups allowed it, Season 6 could be mid-2014 (instead of early 2014) and Season 7 could be end of 2014 to give them lots of time.
Season 4 is already finished, it should be being pressed to disc any time now.
CBSD are indeed working through Season 5 now and it's looking damned incredible.
Release dates (and deadlines) are already set, so while CBSD would love to have until late 2014 for S7, that just isn't the reality!
