How popular are widebody private jets?
Boeing boasts about having sold a number of 747-800 and 787 business jets. Airbus recently opened a section on their website about widebody private jets.
And see Gulfstream:
Industry sources say the company is working on a widebody with a 13,300km (7,200nm) range, compared with the G550's 12,500km at Mach 0.8.

Sure - there are a lot of interior options which just do not fit into the 12 foot cabin width of 737 or 320.
What kind of cross-section could Gulfstream be looking into? And what are the other longhaul jet manufacturers up to (Bombardier, Dassault...)?
