was anything surprising found with the newly released JFK assassination reports?

None.

Yes, but many of them are buried simply because they didn t want to cause more conspiracy theories anymore than they have.

There hasn't been time for researchers to examine them.

It's unlikely there will be much that is surprising. Back in 1992, when it was decreed that the papers would be released over the course of the next 25 years, people did examine them. If there had been any bombshells, then either we would have heard about it then, or the papers in question would NOT have been scheduled for public release on the grounds that they needed to remain classified.
