I am now officially on the PS4. It took a little tinkering to get the UI to how I liked it on the PS3. I definately say that the changes in FF14 from PS3 to PS4 are more profound than FF11 when I started on PS2 and played it on 360 when SoA was released.

My one gripe: On the PS3, I could get the chat textsize large enough for me to feel comfortable reading. On PS4, even at the largest font, it's still a bit smaller than I prefer.
