FYI regarding Dutch Pinball: they DO NOT provide regular updates. In fact, their communication continues to be less than pathetic as it has been nearly 8 months since their last feeble "update".
Early Achievers" such as myself, who DP took $8,500 from 5 years ago now, share your hope that this game will somehow be made. In the meantime, waiting for any info from DP continues to be a never ending series of disappointments.
EDIT: Dutch Pinball FINALLY just sent an update today (of course). See Big Lebowski Preorder thread for more info.
