An industry analyst called Evan Wilson has commented that development problems are the reason for 'inferior' quality titles being released on the PS3 in comparison to the Xbox 360. Wilson also indicates that development challenges will further increase the number of PS3 game delays.

The statement comes as Madden NFL 08 for PS3 is widely seen as inferior to the Xbox 360 version due to sluggish visuals.

Wilson believes the added difficulty for developing on PS3 is directly to blame for the game's slower speed despite Electronic Arts comment earlier this week that it simply takes time to get things right for each individual console. The Xbox 360 has been available for a full year longer than the PS3.

"If your game starts on Xbox 360 you will have to re-engineer aspects of the game to run properly on PS3. This means additional effort," Sony's development team told us back in June. Assuming Madden first started development on 360, the above issue could have easily resulted in slower moving frame rates.
