Yes, unfortunitly , our worst fears are officially confirmed. Playstation 4 will require Playstation Plus to access specific content, very much similar to Xbox Live, where they require up-front payments taken directlly from your SOUL!
But it’s not as bad as origionally skeptisized thaught. Single player games and apps will run like normal. But to play online, however, you will need to sign up to PS Plus to gain access, even with the disc. At the moment, PS Plus is around $19.95 for 3 months, or 69.95 for a full year. But knowing how big companies work, they will most likley go up in price the second the PS4 comes out! Sony has also confirmed that you will be able to transfer your current PS3 membership over.
More news as it comes!
