If we're taking the title 'remakes' so literally, then ORAS should have the same 2D graphics as RSE, too. Just because they aren't sequels doesn't necessarily mean they can't carry over some of the new features from X and Y. I get what you're coming from, but I think when they said ORAS won't be sequels, they meant an extension of the Hoenn region with completely new areas, Pokemon, gym leaders, and so on.
