Quoted from DNO:TK multiball is in the Pro already, and this idea would just kill Premium sales, everyone would just buy the pro and upgrade.
The idea or the tiers is that if you buy the cheaper model, you don’t get all the features, sell the features separate and you also piss off the high tier buyers.
You missed the boat on the premium, so you need to pay what the secondary market is priced at, pretty simple.
But Stern isn’t making Premiums anymore. From their perspective, there can’t be any cannibalism of sales.
