Not happy with DS9 being pushed forward. Unless The Soul Key actually wraps a lot of things up (which, considering the fact that the Ascendents storyline hasn't even got started, isn't all that likely), it feels forced to me.
I think the fact that the Ascendent storyline hasn't started is a plus in this case. We don't know when they're coming, so as long as they don't do anything significant in
The Soul Key, they can show up post-Destiny without being too forced. There are other plotlines I'd hate to see skipped (like the situation with the Dominion), and I do hope we see some gap-filling stories in the future.
It's nice to see some nuTrek novels showing up, although four in a row seems a bit much. Of course, that could be my own preference for the 24th century at work. I'm sure there's someone out there thinking "Why are they doing all these silly Typhon Pact books? I want to read about Kirk!". These things move in cycles.
I'm not sure about letting David Mack play around in the new universe, though; I saw what he did to the last one.
