Hi DEN,
don´t "remember" what will be the next Vault Edition either, but in case you think about buying a modded Tron Legacy for less than a VE let me know:
mine is for sale just around 999 Km´s from you... ;o)

"St le was an awesome experience, does the pro have the same speakers/sound system?"

As far as i know "yes", but custom speech, music & speaker-upgrade are highly recommended anyway...

"Thanks friend, i had tron, fun pin, but not int in another one right now
But if you have twd or st please let me know. Also if you wanna trade, i have few pins for trade.
Lovley T2?? Tz. Pz. Or a sw le under 50playes? Installed convulux plastic protector and playfield protector before ball one "

Thank you for your offers DEN,
just purchased a STLE about four months ago after playing Star Wars LE: Less quality-issues with SAM, better building quality and more gimmicks on the playfield and the cabinet made Star Trek a no-brainer for me...didn´t regret it, so i don´t see it leaving my cave the next years, sorry my friend... ;o)
