Quoted from PPS:jeez ... we are already epic for this year! lol (MM is debatably the #1 game of all ... and MMR builds on top of that ...), so people should have money as not too many new games are out there ... also i'd probably see if we can give some interesting perks around game #2-#N to people for people who got a game #1 ... of course this is all hypothetical ... we will focus on the current game, and when that is all in hand then we can mess around with all of you on games #2-#N ...
Theme will take precedence in most cases, but some 'perks' may get a buyer to spend their money with one company versus another. The competition is only going to increase for dollars in the hobby that isn't growing as fast as the number of companies producing pins, so the companies will need to differentiate themselves.
I think Stern may take the biggest hit down the road as more and more companies produce pinball machines as that is their core business. Jack (not JJP) & PPS have other arms of their businesses. The boutique guys are more than likely not as heavily invested/relying on selling pins for their livlihood.
I'm down with the possible PPS perks as I'm a charter MMr member.
