'fraid my info is not out of date. I have the excavation/study reports :-) hence why I could provide geophys stuff. This was formerly released on 7th September:

The other masses of things found are a lot of very confusing lines (trenches or whatever). The only excavation done was on the ditch around Rath na Rig (the Royal Enclosure - a 100m x 80m henge), which was simply a re-excavation of a part done in the 1950s.

A possible entrance was found to Rath na Rig on the east side, but because its geo phys they don't know yet.

Other things appear to be ring barrows or hut sites.
