It takes a long time to download because of two factors:

The speed of Stern's server and the speed of your connection. I downloaded it at my place of work which has a fantastic speed and it took a long time. No, it does not take that long to install on the pin. Just remember, you will see the pin start up as usual and look like it did not take the USB stick. Give it 30 seconds and you will see the screen change to start the update.......so far the few games I have put on it, other than the light show, no hugely noticeable changes. I was really excited, but now a little disappointed, we'll see what it's like when I get to a belt match. But one, I thought they would disconnect the link between flippers and slammers. Two, I thought that Money In The Bank would finally mean something. That's all I ask to begin with. Oh, and the video changes??? You won't even notice.

I have seen a couple of bugs that have seemed to work themselves out. At one point I could have sworn that I heard my opponents theme song start before it kicked into mine, almost like they are thinking of doing dual intros like real wrestling. All I hope is this is just a quick update to get SPIKE moving and that the real gameplay update is coming soon.

I have had this happen with old updates, I don't think this is new
