As much as I love to support developers, now that most games can be had for half price, or at least $40, within a month or two of release, even if it's only a one-day online sale, I just can't justify day one purchases anymore. Uncharted 3 was the last straw for me. I played the SP campaign three times, got the platinum trophy, getting maybe 30 hours out of it, and that's it, since they cut all the tweaks that would've given the SP more replayability (as a casual player, I can't play that type of game online with any success).
Add to that the cost of pricey DLC for most games, and I think I'll just wait for GOTY editions for the critically acclaimed games. (I'm still kicking myself for buying Batman Arkham City day one, when I could've gotten a GOTY with all the DLC for $40 seven months later.)
I don't see that model changing for the PS4.
