Sorry it might be my misunderstanding. Maybe what Olivier meant is "defeat
human champion" like DeepBlue but not "solve", such as what he said here:
http://teytaud.over-blog.com/article-mogotw-wins-the-first-ever-9x9-game-against-a-top-pro-as-black-38407487.html
We now should win on a complete game like 4 out of 7 games and the job would
be completly done for 9x9 Go :-)
Mogo is clearly on the way to solve 9x9 even 7x7. It is worth mentioning
that Mogo defeated all the pros in 7x7 games in FUZZ-IEEE 2011.

For Zen and CrazyStone, they might not be interested on 9x9, because 19x19
is their arena. Mogo is maybe the best candidate. In the TAAI
conference last year in Taiwan, Olivier stated that Mogo will solve (or
weakly solve?) 9x9 by winning 4 out of 7 games against some top
professional
player.

Ein? That's not what solving a game means.

I think 9x9 go, even though compared to chess in complexity, is still more
complex than chess and that the book will have a little less impact,
although still a lot.
My projection is the opposite: I think that 9x9 will be "played out"
within
5 years. Not weakly solved, exactly, but close to it. Zen and CrazyStone
have the ability to start on that project already.
My impression is that the opening books are routinely worth a few hundred
rating points in 9x9 CGOS.
I would cite Valkyria, which has a version that is playing near the top of
the CGOS ladder most of the time. A comparable version was playing ~200
rating points within the last year, and I suspect that the opening book
knowledge that comes from its long-term memory is the dominant
contributor.
I also cite the Little Golem server, which is dominated by programs that
have opening books.
Based on the work of Mogo and Valkyria, I suspect that if you take a
pretty
good player and create a feedback system then you get a great opening
book.
With an effective branching factor of maybe 2 to 3, you can get pretty far
into the game.
