I really only become "interested" (concerned) when one clearly starts struggling as compared to the others.
I've been following this site for a while and last gen was my favorite kind of war where all three find success and I personally enjoyed all of them. I've only started getting active on these forums recently, though, as I've grown increasingly worried about Nintendo and their wii u.
This war is shaping up to be one in which the PS4 is well above 50% market share, and I tend not to care for that. It's boring and isn't good for the other two, but is also inevitable at this point. Disappointing :
I suppose I do like console wars, then, but only as I prefer them to be in close competition.
