Yup, its coming out on Blu-ray, its gonna cost $30. Not a bad price considering all that is in it; 2 other games, behind-the-scenes, soundtracks, art gallery, 3 mini games.
So you can relax, you can remain off the grid since its coming out on Blu-ray.
But you might wanna consider making a PSN account cuz the CE also contains a 1 month subscription to PS+
