While I don't think Boba will be quite as effective as some think, at 1 point I could see including him in most any list that can take him.
The question you have to ask when you're building a list is whether he's going to do enough, often enough, to be worth more than bringing Greedo or 4-LOM or Zuckuss--or, in some builds, just spending the extra point on something else.
The ships that can carry him are the Firespray, the G1-A, the HWK, the Jumpmaster, and the YV. Two of those are brand-new, so it's hard to say exactly how effective they'll turn out to be. The HWK is fragile, and a ship carrying Fett is going to be a priority target, so that's probably not a great idea. The YV is powerful but not very maneuverable, and the competition for the Firespray's single crew slot is pretty cutthroat.
Maybe I'll be surprised and see him showing up on Kaths everywhere. But what I expect to see is Boba Fett on Mangler YVs, on the generic G1-A as a respectable threat in the range of 25-30 points, and on Jumpmasters with Proton Torpedoes. He's going to be a feature in some Scum lists, but not all of them, because there are a lot of lists where he just won't be able to do much other than take up a crew slot and then die in a fire.
I'm not saying Fett is bad , and my record for prognostication is mixed at best. I'm sure there will be a lot of Fett lists, and every time I see him across the table I'm going to have to have a plan to deal with him. But I don't think he's going to be the reason we take the current metagame and throw it out completely.
(Guidance Chips are the upgrade that will do that, but that's a different conversation.)
