The next Plants vs. Zombies: Garden Warfare game will be revealed at Microsoft’s E3 press conference next Monday, June 15 at 9:30 a.m. PDT / 12:30 p.m. PDT, PopCap Games announced.
So, my guess is that the sequel is again a timed exclusive. Although a full exclusive is not out of the question, seeing how the delay really hurt its PS4 sales (so much that it was given away for free merely 2 months after release).
This is one exclusive I can live without, better this than something I am interested in. I never even bothered to download the first one.
