The DEW Line just got a hold of the RFI for a new Presidential transport to replace the VC-25A as Air Force One in 2017.
Frankly, what's important here is what's not said in the RFP. There's no specification on a twin or four engine requirement or anything about where final assembly has to take place. I think this leaves open the door for A380 as a contender here as Airbus has already demonstrated its willingness to conduct modifications to commercial aircraft in the US.
The PAR aircraft will be a new-build, commercial derivative, wide-body aircraft, uniquely modified to meet the current and projected requirements for the worldwide transportation of the Office of the President. Modifications regarding passenger communications, information systems, interior work & rest environment, and aerial refueling must be accomplished before delivery of the aircraft. The delivery of the first operationally capable aircraft is required in FY17, with delivery of the second and third aircraft in FY19 and FY21, respectively. The PAR aircraft must maintain the highest possible mission capable rate.

Don't rule out the 777-300ER either, there's actually more lower deck cargo room than the current 747-200 which it could replace.
Also, I wouldn't be so quick to say the President won't fly on a non-US aircraft. The VH-71A, which is derived from an AugustWestland EH-101, will transport President Obama beginning in 2010.
So what actually goes into the VC-25A to make it Air Force One? Hey, where's the escape pod?
