Same difference, my point is that it will not be in the standared version therefore they (propobly the marketing department) is limiting content available to the "basic" version.
It's not essential content yet probably more useful and interesting than most of the other fuzzy nonsense like "Behind the scenes" material and "one waste basket full of early artwork" that seems to be released with many special editions lately, which, let's be honest, is usually watched and looked at once, maybe twice and never again by most.
The vehicle is not giving anyone an unfair advantage, it's just entertaining. It's an appetizer, it's a reward for showing some faith in and enthusiasm towards the developers and their product.
I'm actually glad you brought up the term "basic", because that's what you get: the basics. You get what's necessary to play the game. Nothing less, but nothing more either.
Yes, of course this is marketing, but there's nothing wrong with it. Unlike others, they decide to do this not half a year before game release but about 2 months. Unlike others, they're making this actual game content available to all pre-order customers, not just to people who buy the special edition.
This is intended for people who might be waiting in front of closed doors for the shops to open on release day anyways.
That's actually how I'd see it: they're giving those people another reason to pre-order instead of just sit it out and in my opinion, it's a win-win situation: Crytek and EA will know how many people will definitely go and buy their product and the people who want this game will be sure they get it on release day, won't be facing a "sold out" sign (please don't argue about this, I know it's very unlikely) and they're getting a nice little gimmick in addition.
