Boeing has announced that it has completed 90% of the Boeing 777-300ER design.
"We've released more than 10,000 engineering events," said Roger Houck, Longer-Range 777 deputy chief project engineer. "Now, with most of the engineering drawings complete, program partners and suppliers around the world have begun manufacturing the first detailed parts."
A sizeable amount of the plane is being produced overseas which is a "unique aspect" of the 773ER and more information about which countries and companies provide certain parts can be found by reading the full article.
Boeing expects a market for 500 of this model to be built, 45% to Asian operators. Range and weight examples can be found in the full article.
The 777 family has captured 68% of it's intended market and customers include Singapore Airlines.

Boeing is going to great lengths to make their products even more multinational. It's all part of the sales effort to encourage foreign governments (who can influence airlines) to support their local economies by purchasing Boeing. Airbus also subcontracts plenty outside of Europe.
As far as the fuel burn goes, I think Aircraft Economics had an article a while ago comparing the 777-300 and A346. I can't remember which issue or anything.

To BlatantEcho: The fuel burn claims are of course Boeing's though I think they might be possible with a twin-engine vs. a four-engine design. It will be interesting to see how many airlines prefer which design and who ultimately wins this battle of the mini-jumbos.

Two questions; what is the intended range for the 777-300ER and what is the difference between "ER" and "LR"? ER=extended range LR=long(er)range ?? This has always confused me. Does the "LR" designation on Boeing products usually indicate ultra-long range?

John, you've got it right. ER means extended range over the standard versions of the aircraft, LR is long range which is longer than extended range and indeed, the 777-200LR is designed for ultra-long range. I believe the 777-300ER is good for about 7500 nautical miles versus about 8900 nm for the -200LR with the optional added fuel tanks. I don't have my Boeing stats handy but believe these numbers are close.
