I doubt we will see either variant any time soon. the hinged wing tips add weight, but in fact aren't very useful anywhere. AA insisted on their inclusion as an option, but notice that even they didn't order them. The 777-100 was going to be the long range version IIRC, but those crazy engineers at Boeing managed to find a way to make the -200 longer than anyone will ever need.
(Think about it. With a range of over 10000 miles, and the earth is only 24000 miles in circumfrence, you can reach almost any point in the world from any other point with one of these birds.)
