Well in the last number of Famitsu Namco said that they're really happy ith ToV sales ......
- surprised how well ToV sold. Gundam Musou 2 also did well
- Naruto Narutimate Storm (sp?) showed Japan's ability to put out a "super anime" game, or something
- plan to release 5-6 games on 360 this year. since it's HD they are all big titles
- some new IP
- i-mas DLC sales were a massive surprise. even though they don't sell overseas, the dev costs are totally covered
And for Atlus
- developing for 360
