From what I understand of NASA's policy on metric usage, it's per program. I remember hearing flight controllers using metric units, but this was several years ago. Mission controllers used metric just recently during the Mars landings (Spirit and Opportunity). There I remember hearing a mix, so even within the same program there can be both USC and SI.
So yes, hopefully the entire Constellation program, including Orion, will be 99.999% SI (except for that pesky PSI thing).

Yes, it's embarrasing, but I think that "the rest of the world" knows about our special situation.  Their news outles probably translate this to metric.  I doubt that the flight control will switch to metric anytime soon.  Glad to see that the design and flight calculations are metric, though.

Also its not just the design, but the flight calculations.  I get embarrassed for the country every time I hear flight controllers saying "spacecraft xx miles downrage and velocity yy feet/second" going out over international news.

Hehe, that was my first thought when I heard the news.  Glad to see that the specs are all metric.  They're still using PSI for pressure though.  Some things just can't be gotten rid of.
