Good news for all open Alien-preorders: they put a cliffy around the scoop-hole in the production games!!!
Nevertheless I just ordered a pf-protector to be save around the pf-lcd. IMO this area could also cause trouble, when the lcd isn´t adjusted perfectly plain with the playfield. With four screws you can easily bring the lcd in a perfect position but I don´t know how long this adjustment lasts and don´t want to worry after a few matches, if everything is still ok. It can´t be wrong for other vulnerable ares, so I think it could be a value-saving decision.
