No one is telling other people not to think what they want or to discuss points on here, it's a forum, opposing views are to be exchanged and things are to be discussed.
That's kind of the point of a forum.
As for your other points you tell me when the last time a AAA game was launched as a surprise?
With regards to marketing I actually am heavilly involved in marketing as part of my job, so I hope I know a little bit about how marketing works. Surprise factor can be a powerful tool, but I cannot see how doing that with a AA game launch would be anything but a bad thing for sales figures. If you are so keen on that idea, go and have a look at other AAA games and their launches and you tell me when the last AAA game was released as a surprise and how that actually was organised?
Even surprise launches of other products, like technology, don't usually come completley out of the blue. Their release dates are more often than not announced at a scheduled conference used to promote that particular product, a conference that has received it's own marketing in advance.
Sure Sony can release it as a surprise (although the game going gold would be well known anyway), but you know what they are far more likely to actually do? Follow the science behind the metrics that will maximise sales. Sony can also decide they want to scrap GT7 entirely. PD can decide to make the cars in GT7 flying cars, but I'm pretty sure we know what they will do (or rather won't do) in that regard.
2020 being the unusual year it has been doesn't mean you throw all sense out the window and surprise people with a launch, if anything it should mean the opposite. With more people under economic pressure a surprise launch could have a worse impact than normal.
