[quote name='aptanor']I may be switching to a new PS3, and I'm wondering if there's any way to salvage the downloadable PSN games I bought. Are they linked to my PSN account or are they they're linked to the console itself? And how would I go about salvaging them if possible?[/QUOTE]
The games are tied to your account, so you can certainly just re-download them. Since you say that you're replacing your console there's much better option, you can connect one console to the other and just transfer the games and activations between the two consoles, that way you won't need t ore-download anything, will get your save games and preferences and will also not lose one of your five account activations
