	One of the stipulations of the AES competition was that the
algorithm must be free of encumberances.  That being said, apparently
Hitachi chimed in on at least one of the round two candidates claiming
that it was covered under one of their patents.  IMHO...  That was the
kiss of death.

	We do not have to wait for NIST to be prepared.  Someone has already
suggested that the final candidates could be ready for inclusion within
moments of the announcement.  There were only 5 round two candidates.

	We also have some "hints" as to what the announcement is going to
be (although it is a bit of conjecture).  Attached below is the relevant
message from coderpunks.  Take it for what it's worth.

Though NIST is being very secretive regarding the AES announcement,
they let the following rumors leak:

1. There is a single winner.
2. It is not an American design.

If so, this rules out MARS, RC6, and Twofish. But now comes the
third rumor:

3. The winner is not covered by any patent or patent claim
identified or disclosed to NIST by interested parties.

Assuming this is true, there is only one algorithm that is not
explicitly mentioned in Hitachi's claim: Rijndael.
