Well I can't imagine a PSP game costs a lot to develop, they probably figured they could make a run at profit in the long run if a PSP version of a game sold near a half million. But with recent PSP game sales that seems kinda hard, no? Sony must have given them some incentive with Tekken and Soul Calibur on PSP (Kratos anyone?) so they figured it would do better. Plus PSP Go is most likely good profit if they can get someone to download the digital version.
Anyways I think It's more apparent that most companies just don't know how to manage their money well. Konami had good profit last year despite making many HD games, and THQ had a profit albeit very small. I'd imagine if Tales of Vesperia was released WW it would have also given Namco some more money in their pocket.
Either way, look at past Tekken sales and I bet Namco was expecting Tekken to do a lot better. But It's their own fault because they didn't hype it enough and the game (imho) wasn't leaps and bounds better then Tekken 5. It Felt like Tekken 5 to me with more prettier graphics and laggy online (at launch anyways.)
It's just that simple.
