I've been thinking of saving up for a doghouse PC rather than a new console what with steam sales and my desire for a nicer PC to work with. But PS4 is kind of tempting for me, I never owned a Sony system and still don't own a blu-ray player (assuming it's still built in), unfortunately few new games pique my interest (maybe infamous, I had fun on PS3 demos) and honestly I'd rather pay to download a game I want vs. pay a monthly fee to play any game.
At any rate this last gen has convinced me that launch day purchases are 90% not worth it, so I'll just wait and see.
