I have Six (6). As long as you count 'Blue Planet' as one (its like 5 disk.) I got my first player in April of 2010. I have about 50 DVDs.
I, now, prefer to get media on the cloud, but sometimes the discount on a blu-ray is just too tempting. If I got a 3D TV I would get a few 3D ones.
PS Oh, and to make things confusing one, of my Blu-rays is "Halo Ledgens. " (oh the irony.)
