According to Game Developers Research, their new study shows the iPhone platform is more popular with game developers than either the Nintendo DS or Sony PSP. Electronista sums up:

Demand for the iPhone has surged to where about 19 percent of all game developers are writing for the iPhone and iPod touch. The figure is more than twice as high as for the DS and PSP and results in three quarters of all mobile game developers writing for Apple's handhelds.

While no reasons were cited for the level of developer interest in the iPhone and iPod touch, they figure the high visibility of the Apple brand combined with robust developer tools and centralized App Store model makes for a compelling package. 75 million devices on the market probably doesn't hurt either...

Good news for iPhone, iPod touch, and eventually iPad gamers -- with developers come great games.
