Seriously? You got nothing to worry about.
Also, something a lot of people don't understand about advertising. You don't advertise months before your product is out. That is a waste of money. Things like E3 are public relations actions. The companies come to you and let you know what they are working on. You already know about the existence of RDR2.
Advertisement usually doesn't come before one or two weeks before the product is actually purchasable. Because that is a ridiculous waste of money. The point of advertisement is to wake in you the will to immediately buy the product. This will will become less pronounced with time unless you keep wasting money on more and more advertisement to keep it as "top of mind". It's a gigantic waste of money.
Granted, some companies go to lengths, but that is why you see such gigantic "marketing" budgets in games that then require several millions on sales to break even.
So, seriously... if you got to PSN and i imagine Xbox store, you can see a lengthy trailer. The game looks amazing and you can expect similar game play to the previous game. There is no way to mess this up.
What you have to worry about are embargoes that go to release date, not advertisement.
