Why only two now?? What made you guys change it from 5? It's kind of annoying to have to choose which playstation I need to delete an account from so that I can transfer it to another PS3 in a different part of my house. Especially when I need to download something as small as 100kb. And I don't want to pay $20 dollars for it with a different account.
I believe they scaled it back to discourage game sharing and it being unlikely that any one household would have more than 2 PS3s...
You can still have 5 activated consoles for content purchased before the transition. Anything after the transition is limited to 2.
This was done to mitigate people from "gamesharing" which led to a high number of accountsbeing "stolen" or money used from their wallets or even debit/credit cards tied to their account.
