That's an interesting thought, blackfootsteps, considering if NOA would have a say in the final logo. It's the main reason I MIGHT think these are fake.
However, I'm a designer in an advertising and design agency, and one of our core services is brand identity development (aka "making logos"). Rick's right: Photoshop is an industry standard design program, and is often used in the creation of identity systems. I tend more towards Illustrator, at least in the beginning, but to each his own. It'd be crazy (or at least, a waste of billable time) to go all out and do 3D renders or other such stuff in a Preliminary Design Phase (which is what these designs appear to be). Add all the polish to your logo AFTER the client likes your direction.
If these are fakes, whoever made them at least shows a good sense of the design process (check the version numbering system, for example).
