Yes, the Orion will be pin-compatible with the R4000PC and the R4400PC.
Price/power relation means "how many specmark per dollar" too,
but the migration path is more important, I believe.
In case the Orion is available in near future, what we have to find
out, and it's not much more expensive than the R4200, then it might
be a better choice.
The most important thing is availability. The Orion is surely a very
interesting thing, but I would take the CPU which I can *really* buy
when I need it.
