A few thoughts on what was said on that YouTube clip, noting they were stated as rumours and to be taken with a pinch of salt.
I really don't get why you would want to set the show between Enterprise and TOS. All that would do to my mind is limit what you can do for example in terms of what aliens can be in it. Enterprise suffered from that, for instance you couldn't have the Borg, until they shoe horned them in anyway. It also limits what you can do with the wider political environment e.g. The relationship between Earth and the Vulcans, Romulans and Klingons.
I can totally understand the wish to have the coolest hi tech ships etc. That had always been a big part of Star Trek for me and hence was something I found lacking in Enterprise. (And yes I know it gives scope for drama e.g. going into battle with rubbishy shields). But you can't have that if you set the show in that period so that's one reason to start messing with the timeline. But that in itself is in my opinion a really bad idea and just ties the whole thing in knots before it has even started.
I don't understand why you wouldn't just set it after TNG and give yourself a free hand. Other than confusion with the current film series I guess. But the road they are reportedly going down suffers from that even more so.
Anyway as I said that's all based on rumours so hopefully they are not true.
Personally I would like nothing better than a new Star Trek TV show so let's hope it happens.
