If I have heard correctly, AMF used to be a testing ground for Track, Columbia 300, etc. Now, they're are a fraternal twin of 900 Global. The Double Clutch is almost an identical match of the Break core. The Hook! is a modified Code weightblock. Personally, right now, I have more AMF in the bag than 900. Here's the breakdown.
AMF
Hype Reactive
Hype Urethane x 2 (and one NIB!)
Titan
Big Heist
Clutch
Clutch Pearl
900 Global
Bank
Break S75
Break
Link
Nuts Pearl
Seismic
Aftermath
So no, I don't think that the AMF brand is going away. But, stranger things have happened.
