A gamasutra summary of Wada's speech.

So as we know some people are offended/confused by walls of text without sparkly gif animations or videos I'll break it down for you:

tldr:

"Facebook and iPhones are hot potential sources of money and we're more interested in new casual gamers than old Squaresoft Enix supporters because dude that's where it's happenin' right now! Peace out."
Disclaimer: paraphrasing a paraphrased quote always has a few dangers.

Anyway I think anyone who has played previous FF games and then witnessed XIII and XIV has probably already noticed this change in their design philosophy.
