They have already given up that market. Probably smart considering Sony is struggling there and MS has no chance of beating them there. Plus judging by their Gamescom conference I don't think MS has anything new to show while Sony had to cut things from their Gamescom conference and announced they have new reveals for TGS.

Well there goes my hope for Lost Odyssey 2 :(

Then again The Last Guardian is still on vaporware status >_

As long as they are uploaded to the interwebs they are doing the world a good service =D

Also kind of disapointed in them seeing as they have a bunch of XBO xclusive games by Japaneses developers that they should be trying to sell.

I ask myself if nintendo will bring something(besides we alreadly saw at E3).

Oh, definitely.  Microsoft has spent a ton of money in Japan trying to gain traction for the Xbox brand at TGS.  Most famous, of course, is Bill Gates delivering the keynote himself--and allegedly offending some Japanese by being too aggressive with his sales pitch.  They used TGS with the 360 to announce Japanese developed 'exclusives', back before we knew that those deals were timed.  They also went big with Kinect 1.0 with a keynote the year it launched, where they pushed those Japanese Kinect games they paid for, like Steel Battalion, that wierd horror game everyone's forgotten about by now, and that dragon riding game.

They also generally throw buckets of money at Japanese gaming executives by renting out hostess clubs and the like, which I assume will still take place.

Nintendo doesn't even attend TGS

Surprises me they're still trying

I was able to attend TGS last year. Microsoft had a cool Titanfall display with cool babes.

There was almost nobody in their booth trying the XB1 though, compared to long lines to try PS4.  Considering the very slow PS4 adoption, we can't expect much from XB1 sales in Japan.

It's been this way for a while. MS just started doing Gamescom and was on/off with TGS. Nintendo just hates publicity though.
