I'm hoping for the Blockade Runner, too. It's just such a stalwart of the Rebel fleet in the OT in both ANH and ROTJ. Add in the appearances in Revenge of the Sith (a CR 70 instead of a CR 90, granted) , Rogue One and now The Rise of Skywalker, too. It seems like a home run to me, and might have even more broad appeal than the Sail Barge. If it was sized similarly to the Sail Barge it could still have a lot of play value and make for some amazing displays. Add in the fact that Kenner mocked up a prototype back in the day, and it seems like one of those things that has been just out of reach for so long. Haslab might be the way to bring a Blockade Runner to fruition.
Another unrelated item? Patrick from Hasbro said that they wanted to give people time to save their money up for the upcoming Haslab campaign. Are they going to go bigger? I know people have theorized about a Death Star playset. There's been a prototype image circulating for years of a Death Star mockup that was reportedly taken at Hasbro. And it was set up like a sphere with several levels. There's another interesting thing that leads me to think that a Death Star playset could be a possibility. Galactic Trading Post reportedly got officially licensed to produce Star Wars product. But since I saw that announcement they've kind of gone silent. It leaves me thinking that something could be in the works on that front.
As for the people wanting this to be the Razor Crest? I just don't see Haslab as the way to bring that ship to market. I think it could be a mainline release with a similar price point to the TVC Slave One, and sized like the Republic Gunship. It's not a huge ship, and it seems like it would have some mass appeal given the overly positive reception that The Mandalorian has received.
