Looks like this topper is coming at about the same time as the Black Knight topper. This makes the decision of which one I'm buying pretty easy. If this had come out a year ago, I would have bit even at this price point. Black Knight is here to stay for a while. SW is a great game, but will be on the chopping block in around six more months. My collection is mostly SS and EMs, and I like to limit to two newer Sterns at a time for financial reasons. This means rotating out games after a couple of years to bring in a new one.
If this thing has some hidden new feature like the hologram of something super cool, then I might still buy one. Chances are slim at this point.
