The difference is huge imo gameplay and graphics wise.
Gameplay: Blocks, spacing, post game, in&out, pick'n'rolls, defense. All these are improved.
Graphics: Bigger textures, facial animations, lighting. Also Cam's+Lagoa's+SJ's global is exceptional. Cyberface's are next-gen quality and many of them even better.
Go buy the game. It's a steal now with those prices.
