Most MPLS networks use a combination of point to point, frame and ATM facilities as the infrastructure. The phone companies use ATM just about everywhere to deliver voice across their networks. I don't see ATM/FR equipment being EOL'd anytime in the near future.

Maybe the small fact that ATM is fading away and building new

with technology going away is going to explode your operational cost in a few years time. Business grade IP networks will provide you with equal if not better performance than a "dedicated" ATM WAN.
And being replaced with .... ? GigE? DPT/RPR? MPLS?
ATM is a great technology... Unfortunately, I don't think it was ever fully utilized.. From what I understand, MPLS takes some of the good bits and combines it with traditional routing.. But I don't see a lot of MPLS implementations either...
look to the private networks luke... Seriously, many large private ATM/Frame networks are transitioning to MPLS networks because the ATM or Frame gear is/was/will-be-shortly EOL/EOS from the vendors. The costs to run these networks don't jibe well with the alternatives. Now, start the discussion on: "private network" and "mpls vpn" and "oops, hey, that runs over the same routers as that bad-old Internet thing with the haxors and such!" :)
