The problem with this pin is not so much whether it's value for money. Stern have showed that you can keep driving the BOM costs down and charge the same amount or more and people will still buy them.
The issue, I think, is having the confidence to buy the pin and know that PB will be around to back it. As far as I can tell they are replicating the old board sets which have reliability questions around them. We already know the pin is losing the playfield LCD - one of its USPs imo. Apparently the Alien tongue mech is also absent?
The company itself appears to exist only on social media. Who do you go to when you need support? What confidence do you have that they will be around in X years time? What jurisdiction would you need to take them to court in, if it came to it?
The people behind PB have form for phoenixing the company when things look a bit grim. Whose to say that they won't do the same and come back again as "Pinball Uncles", offering 50% off v3 of Alien? "This time we've got it sorted". Maybe hyperbole, but it was a rough ride for a lot of people last time around and its debatable how much PB were involved in continuing to take peoples' money when they knew the company was doomed.
