Some good changes here - keeping the original aqua colour for general board use is good, but in particular going for a more pastel colour palette, as indicated in the stills / video here is a wise sensible move; it is more complimentary to the main symbols. Also nice to see the '2' featuring as a proper logo in the technical sense, on the trail slogans. The new idea to have it read as part of a phrase works effectively.
Onto the areas that could be looked at - the small (Avenir?) '2' next to the BBC logo at the end of trails: this seems incongruous - all use of '2' on screen to refer to BBC2 should use the AMV '2' in line with the idents. It's not practical to use at very small sizes of course, so I can partly see why you've done what you have - my first thought is to resolve this by removing that small plain 2 altogether, but then it is a matter of where to use the AMV '2' instead, and is where consistency comes into play. Could look quite tidy to the left of the vertical bars wherever you wish to position them, but that still leaves the issue of where to the position the BBC logo which should accompany it. In any case, it may require a rethink of the end trail text positioning, if you wish to retain the bottom-left 'BBC' and / or have the '2' still positioned to its right.
A simple but effective approach to the pointers - just one very minor suggestion to create a better distinction between the 'Next on' and programme title could be to try the latter in a heavier weight - but it should be noted at how much more eye-friendly (than the current pres) this already appears to be!
I see no other problems with the actual design and layout, but I do question the overall flow - transitions from pointer to trailer are handled very nicely, but I'm not sure how much they really bring to the look - whether it is an effect for the sake of it, where a traditional cut would serve just as well or even be less 'clunky', perhaps so?
Possibly my biggest doubt is the effectiveness of the short ident cuts between trails. This is more of a question of the choice of cuts and source material, rather than the actual use of short sting-like sequences as presentation elements, which I think are absolutely a fine idea to be looking at - so it's just the approach. Some of the original '07 stings could work better; not sure if I have examples myself anymore, but being SFX-only, they would avoid the slightly jarring mid-music cuts shown here. And for example, the two entirely unique Seascape stings (showing the top and the base of the '2' respectively) might work well in this way as inserts ahead of trails in the same junction.
So despite those doubts about the execution, I can still understand the thinking behind everything. The layout is clear and uncomplicated, palette is more in line with the main identity - overall this some very good, well-considered design. As always, nice to see ideas from you
