By going multiplat, more people can experience the same game you love, the series gaining even more fans.
That will in turn make is possible for sequels coming faster and you can then again, enjoy the gaming goodness follows.
The only reason it shouldn't go multiplat is when the "porting" results in a lose instead of profit.
AFAIK, FF13 is being created on PC, which is then port to PS3 and Xbox 360.
We also know that it's easier to port from PC to Xbox 360.
Logically, it cost them way less to have the game on Xbox 360 than PS3. Hence, less chance of a lose.
So, it not only benefits the developers, it benefits you, too. Why are you resisting?
