Not sure what I need to purchase?

If you will only be playing the PS3 version when your wife isn't on it, you only need to buy 1 PS3 version of the game but she does need both a separate PSN and SE account.

I don't think this is accurate. From what I'm reading, I'll need two PS3 copies of the game as once the first version is associated to my wife's service account, I can no longer associate to mine even using a different PSN network ID.

Maxaud think it like this. Each copy of the game you buy gives you an account.
You and your wife both need separate accounts, right?

The PS3 has technically a 'separate' account from the PC, but you can meld them both into one, but you still need to buy your PS3 account. Of course you can't meld one PS3 account with two different PC accounts, can you?

So you would need two PC accounts (which you already have) and two PS3 accounts (which you plan on buying).

*deep breaths* Now the entire shebang about PSN ID and SEID I don't really know how it works, but presumably each PSN ID can only hold one account since supposedly only one person uses a single PSN ID, so you might need to make a new PSN ID account for the wife, but I think that's free? SEIDs APPARENTLY allow for multiple people to share them, don't know for sure.
