I will definitely buy for EA, but I'm pretty good about playing once and uninstalling. By the time the game is released, I'll be ready to play through Act 1 again and it will be relatively fresh.
I may have a tough time uninstalling after playing it - hopefully Dark Alliance or Solaster Crown of the magister come out inbetween time..
Cyberpunk 2077 will be released in November and it would be commercial suicide to go up against it. That leaves BG3 a 3-month window between early access in August and possible earliest full release in October the way I see it. Given a Larian lead designer recently stated there would be a "massive, massive amount of things to do", possibly X-Mas would be more realistic or this time next year even! Loads of games coming out by then. Vampire: The Masquerade – Bloodlines 2 is likely releasing sometime before Cyberpunk. Not too impressed with what I've seen so far, but liked the Troika original.
