Yeah, people will leave if the conditions are right. I have to say, it took me a while because I'm big on trophies (steam achievements are kind of trash compared to it), the thought of having to start my library from zero is also not very appealing, plus PC can have some small annoyances.
That being said, with Square Enix clearly signaling that they're stopping their launch exclusivity, Sony's first party games no longer being exclusive forever (and not as appealing as they once were), and my desire for better resolution/performance all worked together to a tipping point and I caved.
