Though this is pretty much dead... I figured I'd chime in and give you all an update about the card.
Applied, got it, came. Same thing as the regular Amex platinum card. The only difference seen was theres an extra page in the terms and conditions that states the extrea rewards you get as a mbz user.
Doubt I'll ever use the mbz rewards, just wanted the 50k bonus so figured I'd give Amex an extra 25 bucks for the security of knowing that I'll get my full bonus.
