Couple Questions about PSN games

I see that Puppeteer is on a great sale for the PS3. Does anyone know if I buy it on the PS3, and when and if they make a PS4 version, would I need to buy it all over again?

Same thing goes with the newly announced Guacamelee Bundle offered starting today.

While it is possible that, if they do make a PS4 version, they'd make it upgradeable for $10 like several other games but that seems to be an option just for the newest releases with versions for both systems. Odds are good there will not be a PS4 version. Same for the Guacamelee game bundle. If you are interested in the games just go ahead and buy them ($7 for Puppeteer is a steal and if I didn't already have the disc I'd jump on that).

I wouldn't expect a PS4 version, so don't let that hold you back from enjoying a very good and unique platformer at an insanely low price.
