As asked before WHERE WAS IT ADVERTISED?
That's a really clever response since Tesla doesn't advertise period because Elon himself is the promoter/ advertiser in chief. Elon and Tesla has said enough about this that it doesn't matter.
Remember, they announced that the new Model S will have advanced gaming and even did a joint announcement with AMD touting the PS5 level of gaming performance in the Refreshed S (prior to launch). They then included Witcher 3 screens (just like the Ocean given the context) on the product pages showing the interior of the refreshed S from the beginning.
Finally, at the launch party which was covered by the invited media and YouTubers (ugh), they had demos set up for people to play Witcher 3 and Cyberpunk with Elon again touting (advertising, bragging about, illustrating, or whatever) the gaming capabilities of the Refreshed S.
To be fair, Elon did Tweet (for what that's worth now) that a retrofit would be available so I am not upset or concerned yet.
Crap, he could have just rolled out Witcher 3 and maybe a few other games (and created an app store to sell and make money on Tesla car only versions of these games) and that would be what I was kind-of expecting based on what was announced at launch. Steam integration is MUCH BETTER and opens up for many of us our existing library of games. If I have to pay the cost of a game or 2 or 3 to get the retrofit, I won't be happy (at all) but will most likely end up saving money in the long run and getting more games than I would have if Tesla had created its own game app store to sell us a handful of games.
