I personally don't think that we'll get much at Gamescom (wasn't last years Gamescom just a recap of what happened at E3?), but TGS is a different story. I don't really rely on TGS for Nintendo, but SS is a pretty big game so maybe we could get a new trailer/demo or maybe even more concept art at TGS. And then there is the off topic stuff like Square Enix...so yeah I'm hoping TGS will bring some new SS food to the table and maybe some reports about any other Nintendo-based games if they wish.
