I see... Thanks for the opinion from personal experience. Will help a lot.
I think Xbox360 is a gen older, PS4 seems more comparable to the Xbox One, isn't it?
I'm thinking in the direction of the new PS4 Neo (also referred to as PS 4.5).. There's still a huge time left, for its launch so a huge time for saving money for it too! Only have a HD TV now, but can consider a 4K TV for the future.
From what I know, the internals will have almost the same architecture, just that much stronger for the 4K support. So, most of the games will run commonly on both PS4's.
PS: I'm considering it for long term video game business purpose.
At 30, I'm not really into games a lot, although I might enjoy some serious gaming myself too, agreed.
