the PSP port gives credit to the theory that the game was a flop, or at least that it did not met their expectations.

I tend to agree. Why release it on the PSP? It cannot be a straight port due to the lack of touchscreen, and they already stated exclusive content. If the game would have made the money they expected, then they would not need to invest in a PSP version.
