Admitting that EPIC did not pan out is one thing.  But transforming an
EPIC architecture into an OOE one is another.

If this were a true deep down transformation of the architecture, it
would mean that upgrading from Tukwila to Poulson based system would be
a massive undertaking for customers who would have to use new compilers
to recompile their software and more importantly, because of the new
compilers, retest/certify all of their applications.

This is why I think the OOE nature will be very limited and work only
within what the existing compilers have told the CPU can execute in
parralel.
