I don't believe all these Sony games are going to magically all take several years until they are ported though, because that would be a super slow and foolhardy plan.
Imagine trying to drip feed a new market you want to make use of so hard, and then realise you're acting far slower than your competitor.
I would also say it's not "non credible", because I've seen fanboys like Jaytechtv spout shit where Horizon wouldn't end up on PC, yet it did, same with Days Gone, and that ended up on PC as well. Don't say it now, say it in 10-20 years when actual time has passed to say it safely with an absolute guarantee, because saying "it's not true, thus it won't happen" and then it happening, just means someone is going to be eating copious amounts of crow.
Step right up come on in, feel the buzz in your veins, I'm like an chemical electrical right into your brain and I'm the one who killed the Radio, soon you'll all see
So pay up motherfuckers you belong to "V"
