Default Xiangqi/Shogi engine strength Was:( bitboards)

Just curious...
What is the current status of Xiangqi engines? Are they "GM" strength? Are
they "World Champion" strength?
I seem to recall that Xiangqi is around the same order of complexity as
western chess. But I would guess that, in general, Xiangqi engines are not
as strong because there are less Xiangqi programmers and the evaluation
functions aren't as finely-tuned as in western chess.

On a related note, what is the current status of Shogi engines? Shogi
presents some interesting computing problems.

A quick comparision between western chess and Shogi:
board size: 8x8 vs 9x9
piece types: 6 vs 8
starting pieces: 32 vs 40
captured pieces: disappear vs recycled (known as 'drop')
draw occurrence: frequent vs rare

Keep in mind that it is a slightly different game so there is no
diagonal bitboards, the board is larger, and special stuff has to be
done for blocking jumpers.
