Boeing says that Arik was offered a B777 3rd quarter 2009, but could not agree on a price to reconfigure to Arik specs.
The airframes are on the assembly line now, beginning late 2010 delivery. My personal thought, and this is purely conjecture, is that we'll never actually see a wide body Boeing (well, maybe a 787 way done the road). I think that the flood of Airbuses on the market will somehow replace them.
And, that probably makes sense. A340 and A330 are common types (differences training), so the same pilot group can fly both.
Today, Boeing should have delivered "Q", the 17th 737, this one an -800NG.
