I can't say I'm overly keen.
The colour scheme of the playfield and art style are really similar to Metallica, so right off the bat it doesn't seem that fresh. As I said before, the art's much less edgy and detailed than a lot of Zombie Yeti's stuff. Upper part of the playfield looks really crowded and unappealing, and toys still look really cheap compared with JJP and DP. Backglass still a bit derpy. No LCD. LE's cabinet art and colour scheme looks bad and really doesn't match the playfield at all IMO. Pro cabinet looks good, Premium superb. Though again it's another another Premium without flipper button guards. The rumoured laser beams didn't make it.
I don't see how most people in EU / UK can justify this if they're buying one NIB game per year, or one every 2 years. Big Lebowski will probably be cheaper than a GB Premium in the UK, and immensely higher quality than the LE. Depending on what Heighway do with Alien (i.e. how good it is), a Heighway LE won't be much more than a Pro. I'm guessing the GB LE will be £9000+ in the UK ... but then that's JJP territory, with Hobbit becoming available and the Lawlor game due later in the year.
Yeah they've made more effort in some areas (art), and it's a good theme, but it seems like another by-the-numbers game with little to no advancement in build quality or innovation.
