I believe that the design Boeing offered to the USAF was not the
same as the one currently being built for Italy and Japan- it's
based on the 767-200LRF airframe rather than the 767-200ER. And
while the airframes themselves have been flying since 2005, they
only started testing the refueling systems last year and none have
actually entered service yet. First deliveries are supposed to be
in the first quarter of 2008. It's still been around longer than
the A330-MRTT variant, but the disparity isn't as large as it first
appears.

Boeing still has a great deal more experience building tankers, of
course, but I'd hesitate to call either of these designs
significantly more mature than the other.

I recall Boeing's Advanced Tanker was some kind of hybrid, like you
said it's based on the 767-200LRF but it has a different wing. (can't
find a source for this) The 767 has been around longer than the A330
for sure, but I don't think that lessens the risk in developing a
refueler based on that plane. Either airplane would be a huge
improvement over the creaky KC-135 (now I'm reading they may not be
in as bad a shape as was previously believed)

Per Aviation Leak at:

The airframe that was actually being offered, the -200LRF, appears to
still be in development. According to the article, it had the
airframe of a 767-200, wings from the -300F freighter, and cockpit and
empennage from the -400ER model. The 767 is a proven airframe, but
I'm not sure that putting together all those parts and trying to make
them work together is a low-risk strategy.

It's been done for years by all sorts of manufacturers, including
Boeing.
