If I like the game when the code is mature, I would buy a Premium. If, at that time, there are LEs available, I might buy one of those, but I really don't want the backglass or the COA/signature bs. I certainly don't want to pay for those.

Buying a pro is not an option for me. I want the full game, or nothing. These are toys, and I can live without them. I am not going to buy a pin until it is complete, so I am not going to buy an LE now just in case it turns out to be a great game.

At this point, if they did kill the Premium, and still release games with incomplete code, they have lost a NIB customer.

I wait about a year as well. I played at least 100 games of both AC/DC and Metallica before I purchased them. That seems about right to me. I also had a year of reading threads here so i knew of any potential issues in addition to my own playtesting.

I am not a buyer until the code is complete, but I prefer the Premium model to the LE. I would rather give that extra $700 - $1000 to Pinball Refinery to make better improvements. If there is an LE still available when code is mature, I may buy it, but I really don't want to pay for some stupid certificate and a signature. Those are 100% useless to me.

I suppose it is possible for some after a while, but since the pro is not limited, there is really no reason not to wait and see. We all know that it is a possibility since Stern answered that question when asked. I can see a Premium buyer buying an LE if they really can't live without a game they have never actually played, but I just can't see them going the other way to a Pro this early.

My choices would be:
Premium after code maturity
LE HUO after code maturity
Nothing

Those are the only three options I will consider. I think there are quite a few Premium buyers who feel the same way.
