Managed to snag a demo of the new Core XC. So a quick and unauthorised review after testing over two days, one on river at Applecross, Perth and second in the ocean at Lancelin.
First, current available in one color, Core black from 2.5 to 7.0. I somehow convinced Mark of WA Surf to loan me his 4.5m for a demo over the weekend.

I forgot to ask for a leash so I just use a calf coiled board leash to my belt.

Canopy is latest gen taut. Core's well regarded kite triple rip stop so I suppose it will last. I tried to weight it on bathroom scale, i.e. with and without wing, about 2.7kg. Felt light flying in hands even in 10'ish knots.

The inflation system is well figured out. Nice positive quarter turn locks in. You can pump both leading edge and strut independently (lock the hose) or one go (unlock the hose and plug the other inlet). Likewise you can deflate thru either or both together.

Yes, a gen 1 mini-boom! Ok, I think the German design team sat back, decide it was time and tested many latest wings. Its one of the nicer mini booms (for my hands anyway). Rubber coated but not sticky or too soft. Feels they will last.

Leading edge handle thick neoprene knuckle savers and the wing flags well and no funny flipping or movements .. locked in nicely.

I am not a big fab of windows. Its there, I can see thru them while winging across and slightly upwind and its at least at the right height.

Generous anti scruff padding where its needed.

These actually holds the leading edge bladder in place mid span on each ide of the wing to prevent twisting.

To deflate, plug in those small tabs and it deflates quick due to large openings.

Comes with usual modern repair kit and manual.

Nicely built handsome bag.

I never owned a proper mini-boom. Had the Echo gen 1 boom, Cabrinha X2 soft mini-boom and lately with Naish Matadors, F-One Strike v1 and Ozone V2 Wasp. After 2 days of riding the 4.5m in 12/13 - 20knts (gusts) in both flat water and open ocean .. after first 5 mins figuring out where to put my hands for reaching and upwind .. its a nice latest gen wing. Very stable, pumps efficiently, tractors upwind as good as the Matadors. Not as light as the F-One Strike but never felt its weight even when sculling back in 6-7 knots on my 56L Amos Nitro board.

Had fun. Have to return it tomorrow to WA Surf. Not sure how much $$$ yet. But feel I will be liquidating some wings soon unless I demo something that makes me happier over next few weeks

Foil - FYI, I ride Axis HPS830/375P/Ultrashort Advance Black with 86cm v1.2 carbon mast. Weights 64kg dry. Thanks, hope was useful.
