Just got mine too, like this better than the 2.0 as much as I loved that one this just looks better proportioned. Love that you can tilt the head now too, really adds to expressions when posing.
No issues with pegs either, I did note mine were a little stiff but its quite warm today so might be contributing. Certainly don't feel weak and switched hands and taken foot off to inspect.
I only have the DP2 figure. They do stay in place but don't look seemless, there is gaps, I think they are ever so slighly smaller than the new eyes. It could work but there will be slight gaps which ruins the look imo.
