I'm going to reserve my final opinion until I PLAY the game, but buying one early is not in the cards for me on this particular machine for a few reasons.
First, I was hoping for a movie themed Deadpool pinball.. love the movies and thought it would be a must-have. I know the "comic purists" love this version, but I don't read the comics and I don't watch the DP cartoons, so it's just harder to relate to the theme as it's presented in the pinball machine. Most people I know only like Deadpool because of the movies. "it is what it is".
I kind of thought that this theme would be like what Metallica is to music pins... raw, in your face, and crude. Not really feeling that with the Saturday morning cartoon animations. "Little Deadpool" call-outs to me are like nails going down a chalkboard. But if the game plays fast and has good flow, I'm sure I'll be more focused on gameplay and can look past it (especially if it's not repetitive like "ok, who brought the dog!".
And since I mentioned flow, I would say this game is fast and looks great as it plays... smooth as butter ramps, sweet shots, and overall I'm impressed with the layout as I saw it. Code looks fantastic also, at least in its early stage. Artwork checks all the boxes for me also.
So while I'm not "all-in" at the start, I'm not "all-out" either. I'm hoping the game does indeed kick ass to me, but I'm taking this one on a test-drive first before I buy.
