the first time I heard of such a thing was with Tomb Raider on xbone, it took a little while before the publisher was allowed to say it was timed exclusive (and it was much better on PS4).I cant remember when Sony did the say for a reveal embargo? Actually wondering if they did?
What I recall from Sony's presentation back then was that each trailer was shown with one of the following:
- Console exclusive
- Timed console exclusive
Making it clear what the deal was. Obviously you can't expect a platform holder to show all platforms that do not belong to them at the end of a trailer, but at least do not try to obfuscate the information about the game coming to other platforms at some point.
