The last few games will be getting updates.. do you really need a crystal ball and doctorate in metaphysical incontinence to figure out what that means?
There are very few companies that tell you exactly what is going to be updated and what that update includes. Very few. If it bugs you that much, then simply put don't buy the games until YOU feel the code is acceptable for your tastes. People feeling like they own 'boat anchors' are simply reading too much gossip and thinking too hard about it which ruins the fun of pinball in the first place. You're supposed to enjoy the game and be happy as it evolves over time, not stress out and hate everything because some bell doesn't ding yet and you want a report out of why.
History shows that nearly every game evolves and becomes quite good with refined code, but there's obviously no set schedule for it and I don't blame them. Stern usually only says what they are comfortable with, can you imagine if they said it would be done on X date and missed the date? People would be on suicide watch here. Hell, JJP took their updates to their private forums because of the lunacy.
