"...House is keen for Sony to remaster old PlayStation games for this new audience on PS4. We're already seeing the fruits of this with The Last of Us Remastered on PS4, due out soon. Naughty Dog's game launched on PS3 in June 2013, and Sony believes there are a significant number of PS4 owners who never played it."
—Wesley Yin-Poole, Sony: PS4 targeting Wii owners who skipped PS3 and Xbox 360
If the greatest hits of the PS3 are a substantial draw for the PS4, then maybe the console should have been - oh, I don't know, backwards compatible? Maybe they shouldn't have fractured the PlayStation platform to begin with, so that they wouldn't need re-releases to try to patch it back up.
I'm sure somebody thought it was a great idea to repackage these games and sell them for launch prices again. But this comes off as an argument that now is a great time to buy a PS3, not a PS4. You can get one and the same games they're using to sell the PS4 for a fraction of the cost, with a much larger library of other games available to try out next. And if you're coming from the Wii, the graphical jump from SD to HD will be plenty impressive - way bigger than the jump from PS3 to PS4.
I don't know who this is really for. If you already have the games, there's no real reason to pick them up on PS4 again. If you don't, it's still better to get them on PS3. A backwards-compatible PS4 would have been more appealing for new and existing customers alike.
"It seems like [a] crazy decision. Consoles gain value as their library grows. They also gain brand loyalty. If I have a bookshelf full of Xbox games at home when my Xbox dies, then it's a safe bet I'll just replace it with a new Xbox even if there are other, cheaper, more popular, more reliable devices out there. I'm tied to the machine by the library, and the longer I'm with the machine the bigger the library gets. It's almost like a cell phone where the penalty for cancelling the service grows over time. A lot of other businesses would LOVE to have this kind of soft, incremental lock-in.
But if the new generation isn't backwards compatible then I'm cut off from that library. The incentives tying players to the platform are gone. When you break compatibility you're setting your customers free to dabble with the competition and begin a process of gradual lock-in with them."

For my part, I still have no PS4 and I still have no concrete plans to buy one.
