I thought the Nightwing Prime guy died in the hospital? I only skimmed a pirated copy of the issue so I don't remember it clearly though. The thing with Bea is that Jurgens is going to address her situation given the solicit, but she is also a character no one cares about and will be forgotten for good after it. So it is a bit frustrating wasting more time on a character that has no value in any future story when people already don't like the story she is in now.
But if reading comics for as long as I have has taught me anything is that the actual important things readers would be interested in, like what happened to Wally in Heroes in Crisis, won't be touched on in Nightwing because it was never present in the Ric story. Jurgens isn't going to suddenly touch on the Heroes in Crisis story and its fallout that is a year old now when they purposefully ignored it. Creators like to keep these stories self contained. Even the Alfred thing will probably not be dealt with other than a quick panel at most given they think that special Alfred funeral issue was enough for it. Same with the Titans. They won't be touched on either since they were never present in the Nightwing story. It is likely that the issues after #75 will be just tying into Death Metal like you said given they don't really have anything else.
