I'll repost a specification table from the first thread; the -500 and -600 data are from Boeing 747-400 by Peter Gilchrist and the others (I think) are from Boeing press releases. The "-7I" is the original 747-8I with a shorter fuselage stretch. Specs obviously changed over time during the various programs, so other sources may have different information.

What's really remarkable is how ambitious the -500X and -600X were in terms of gross weight, capacity, and range. If I had more room, it would be interesting to compare them with the A380. Too bad the stars never aligned for that program, although given lackluster VLA sales to date, it probably would not have been a commercial success (and the cost might have crowded out more important projects like the 787).

The 747-8I is in many ways the modern version of the original 747-500X.
Boeing 747-8I and Boeing 747-500X
Boeing went through about a dozen different development models of the 747 after the 747-400 entered service, eventually ending up with the 747-8.
The 747-500 and 747-600 had some traction, with TG and BA originally signing on to launch them, however the 1997 Asian Financial Crisis knocked TG out and BA re-evaluated the need for such a large capacity jump and therefore also pulled out, eventually drifting towards the A3XX (ordering the A388 about a decade later).
LH was always interested in a larger 747 and expressed serious interest in the 747-X - especially after 9.11 impacted TATL traffic, which was to be a focus of their A388 fleet. They were disappointed when Boeing canceled the 747-X and privately continued to express interest in a larger 747 model, including suggesting Boeing re-launch the 747-X. So I have never been surprised at their ordering the 747-8 nor did I ever feel they would walk away from it, even if they had ended up being the only operator of the type.

Quoting N328KF (Reply 5): But wow, the 747-600X was gorgeous! That long wingspan really added to the gracefulness.

BA ordered its second tranche of 777 around that time. I wonder if that was in substitute for the 747-600. In the late 1990's BA CEO Roger Ayling resigned and they were "right sizing" teh fleet. BA was going premuim with its Club World Class and cutting back on coach. BA's 777 tendancy with heavy J class planes leads me to say the 777 was the "right" size plane.
