"Until we can ensure that everyone can enjoy the full social connected online experience, we will be postponing the release of [Driveclub's] PS Plus Edition until further notice." - Shuhei Yoshida posts on Driveclub's Facebook page about the racing game's ongoing issues.
On the one hand, it's pretty damn embarrassing that Sony and Evolution can't get this thing working so many weeks after launch. I mean, c'mon.
On the other hand, this is a problem caused by how well the game has sold and how many people are trying to play it, and they've gotta love having that problem. I'm sure the primary cause was "we expected everybody to ignore this thing, we didn't even advertise it."
