Square Enix director Motomu Toriyama has confirmed trophy support for Final Fantasy XIII for PlayStation 3. IGN translated some of his word in an interview with Famitsu:
Toriyama also shared some technical details on the game. Save data will take up 500KB. Trophy data takes up 3,080KB (yes, it looks like the game supports Trophies!). In case you were stocking up munitions for a big system wars battle, there won’t be a hard disk installation.
Trophies are always welcomed, but I found it odd that there won’t be a hard-drive option. If it decreases load times and optical-disc access, I’ll always go with that option. Curious, eh?
