The 2009/2010 State of Game Development Survey has revealed that the iPhone development platform is becoming increasingly popular, while the Wii is starting to see its decline. That seems to be the exact opposite of what we were seeing a couple of years ago – then, the Wii was selling out from every store shelf and the iPhone didn’t even have an App Store yet.

So, what’s to blame for the shift? The slowing demand for the Wii, for one, and also probably the fact that the App Store makes it easy for indie developers to get started and make a profit.

What about the rest of the stats? The iPhone/iPod Touch is easily the most popular mobile platform, the Xbox 360 is king of the consoles, and 70% of developers were working on titles for PC/Mac.

Do you think the slowdown in Wii title production will lead to more quality titles, or do you think the developers that remain are the ones working on stuff that ain’t so great?
