From the boxart head, and shoulder panels, it does look like it could be the MU Masterpiece sentinel.

Curious who else will be in it though. Likely wolverine since he's on the front. So the old man Logan with new head seems about right. Maybe 3 other figures though depending on cost and size.

If it's legends 6'' I'd assume at least two figures plus sentinel. If it's 4'' I'd assume 4 figures plus sentinel.

That's based on the assumption from box size it may lean on a 99.99 retail value. If it's at less, maybe less figures.
The sentinel ups that by 50 USD. then from there, it's whatever the cost of additional figures.

So if it's at 69.99, likely one sentinel, one 6'' legends figure. If it's at 99.99 either 4 3.75'' figures, or 2 6'' figures. Though it could also be a 4'' set at 69.99 depending on the electronics and accessories that could be Logan and Sentinel as a nod to their previous Wolverine and Sentinel release.

Whatever it is, definitely betting on it has Logan and a sentinel. Scale, price, and what else are the question though. Based on scale though, I kind of think they may actually do this as a 4'' figure release. The sentinel seems to really tower over wolverine in that pic, and a 6'' figure to MU Masterpiece sentinel wouldn't have that same effect.
