If it makes anyone feel better -- I'm maybe 125 + games into my LE (I've had it for less than 2 weeks) - and so far the playfield looks fantastic - no pooling, no chips, a fraction of the dimples that my Monster Bash LE had in it's first week - with fewer games (not a knock against Chicago - I love that machine too!)
I can't imagine I'm in the minority on a quality playfield.
I'm spectulating there may have been a small batch perhaps not cured properly? But I wouldn't worry about it guys - just enjoy it when you get it (or just cancel your order, or give your place up to someone who wants the LE now.)
You'll be so busy being dazzled by the sheer technical achievement this machine represents for JJP - you'll not worry about all the minor imperfections if yours has any.
