no im not saying that SE is running out of ideas or something, but merely pointing out the simmilarities!
and could u post this on the first post:
"Gravity
In a developer interview, Motomu Toriyama stated that the E3 Trailer shows what is known as the 'Gravity Bomb', known as the spell 'Gravity' in previous games. Presumably, it refers to the electrical energy field that surrounds the young woman shown in the trailer. It has some unique properties by allowing her to defy gravity, as well as allowing her to use it as a weapon.


Graphics
The game runs on the White Engine, an all-new exclusive next-gen engine built for Square Enix's future games. It was originally planned for the PlayStation 2 but was later moved to the PlayStation 3. Realistic CGI cutscenes can be created using this engine, and the quality of these cutscene sequences has never been achieved before on the PlayStation 2 or the PlayStation.


Online Option
While players will still get to experience Final Fantasy XIII as an offline game, Yoshinori Kitase has stated in the developer interview that players will also get to play Final Fantasy XIII online as well"-wikipedia

ye that's it!
