I did find it a little weird. I don't eat anything that would have "microwave directions" on it, but I use mine a lot for certain leftovers. If I had a family though I could see not ever having leftovers.
That was announced at the Sony E3 press conference.
It was, however, announced as something like "Drive Club: PS+ Edition," which I'm pretty sure they came out and said later that it would only include select cars and tracks and that they'd offer the ability to upgrade to the full version.
Seeing that in one of their videos they felt like they needed to mention that the PS+ version contains the same social features the retail version does tells me that it'll have a limited set of cars and tracks. If anything it's like what MS is doing with KI.
