I'd go into it expecting that it could take 3-6 months so that you're not upset if it takes somewhat longer. They are ramping up, but based on my experience they are currently getting about 1 machine a week out the door. It looks like there are a lot of games in process now though, so they may be close to getting up to 2 games a week. Not sure, but my educated guess is that they've shipped around 25 games so far. Your best bet is to call them. I'm sure they'll give you an honest estimate.

I also sold Shadow to make room for AMH. AMH has some big shoes to fill but I'm sure it is up to the task.
