I just bought a high spec - 2.5ghz i7, 750GB 7200rpm, Hires AG - 15in Pro two weeks ago and don't regret it one bit. Why? I need discrete graphics, multiple drives (I now have a SSD + the 750GB drive), and upgradeable RAM (I have 16GB now, and will have 32GB when 16GB dimms become more available).
Essentially, I need a mobile workstation. And always have, a long string of machines dating back to the pair of a IBM A30p and a 500mhz TiBook.
I would have jumped on an air if they had discrete graphics and upgradeable ram. I would be able to live with the lack of additional storage and lack of antiglare screen, but I can't live with the soldered RAM and Intel graphics. Any video editor will tell you the same.
So if Apple revamps the "pro" line with what they are saying they will I will buy a Macbook - another Pro to replace my WhiteBook, likely the low-end 15in with a HR AG panel. It may seem excessive but the WhiteBook is basically my "home computer" and the Pro is my on-the-go workhorse that I hope to get 5 years out of.
Anyway I doubt Apple would drop the pro line. I've had Macs since 2001 (TiBook 500, iBook 500, AlBook 1.67, Mini, WhiteBook, Pro), and I think with every consumer revision there's talk of the Pro line being melded into it, but it's never really happened.
I hope not, as well both for my wallet and for my longevity of laptops. I had the TiBook until the 1.67ghz 12in AlBook came out, and had the AlBook until I bought the WhiteBook. I had a series of PC laptops (A30p, T43p, Dell 8600, T61p, Dell D620, and HP 8440p) along the line that were doing the heavy lifting, but man am I glad to be back to having my high-end workhorse being a Mac. If you couldn't tell I had a LOT of PC's during that period...

I just bought a 15" AG 2011 for $1600 brand new. Best purchase ever.
Agreed. The AG panel is the most gorgeous laptop panel I've laid my eyes on, maybe second only to RGBLED panels on the Lenovo W520. If it's discontinued, I'll buy another one before it rides off into the sunset.
