So the winner is, not totally surprisingly, Stockfish 2.31! That engine certainly was one of the top favorites. There were also some nice suprises! Ivanhoe getting to final surely counts as one of them, while it can beat anyone in a single game (or match as was seen). I was also surprised not so pleasantly how quite a few engines had to be disqualified simply because I could not get them to work in Arena. Perhaps in future some of those can be fixed to work ok, thou I tried with every different settings always. Also the top-4 engine Tactico Pro suffered performance difficulties early on, namely it lost games by making illegal moves, another major trouble with chess engines at times! However, after changing it´s setting in Arena it worked perfectly and almost took the whole tournament! It really beat some major players, such as Houdini 1.5 and Deep Shredder 12. And it also plays with interesting, tactical style which seems to really suit bullet level play, as might be expected of course. Fun tournament, and next one will come thou as a 32-engine version.
Then also the FINAL8-tournament was played. And to the results:

Tactico Pro! What a performance! Something like this was expected after the KO-tourney, but winning this much tougher competition with 3 point margin losing just one single game to the runner-up and KO-winner Stockfish 2.31, is a stunning achievement! Well done. It is worth to noting that it actually played quite evenly against other top-4 finishers, but crushed the weaker placed engines mercilessly therefore being much more consistent.
Otherwise quite a leveled tourney in the end, excluding the eight placed Komodo3 that perhaps does not perform so well in bullet chess, thou the competitors really were best of the kind also. Houdini continues to underperform, while former king-of-the-hill Rybka 4 did not perform that great either, but ended with perhaps still decent 6/14.
Here is my ranking list at the moment for the best engines I have for bullet level 1/1 chess based on these two played tournaments:
