From Aviation Week & Space Technology:
Only the 63,300 lb. thrust General Electric CF6-80C2B9F is a committed engine for the 747XQLR thus far. It is a variant of the 62,100 lb.-thrust -80C2B5F that GE offers for the 747-400 and 747-400ER.
Boeing is in talks with Pratt & Whitney and Rolls-Royce as well, and both are expected to join the program if it is launched. Pratt will offer an adaptation of the 63,300-lb.-thrust PW4062 that it has on the -400/-400ER. Rolls would switch from the RB211-524H8-T on the 747-400ER to the Trent 600, a company official said.
Having all three engines available will be a key to the -400XQLR's acceptance, particularly in Asia, where the new version is targeted. For instance, SIA and Korean Air are Pratt & whitney customers for thier 747 fleets, while Cathay Pacific flies Trents on its 777 fleet and All Nippon Airways and Japan Airlines fly the CF6-80C.
It appears that Boeing has learned a lesson from the 777LR.

The 772LR/773ER are niche aircraft, not enough frames will be sold to justify 3 engine makers producing engines capabale of 100-115k lbs of thrust.
I am Rolls and PW didn't care about making a profit, they would have jumped onboard these ER 777s early just to get their engines onboard, and Boeing wouldn't only have one supplier. The "Exclusive" part of this deal is to make it sound like a huge selection process weeded out the GE as the best of the best, when really, with only one supplier viable for such a niche plane (read: not +500 orders as 744), GE was able to do it most efficent, and no one else wanted to bother to be competition.
Lots of work to get expand an engine from 90k lbs thrust to 115k. Barely any for the 744XQLR, just get a 62,000k lb engine up to 63,000. All three can do that easily, hence the competition.

Very true. I should have stated that Boeing announced the fact that all three makers will be a part of the project up front. Resulting in no additional alienation. However, I can't wonder that if all three makers had the chance to get thier hands in the 777X pie, that there would have been more interest than there currently is.
