I don't believe it yet. But I can see the logic. They're kind of in a Half Life 3 situation with regards to Random Access Memories. At this point, there's almost no way imaginable they could top it, and anything they do come out with will probably be compared unfavorably.
I thought RAM was already on the downturn. They peaked with Discovery and Alive 2007 in my opinion.
To me RAM sounds like an Air album, not a Daft Punk album. I don't consider that a bad thing though.
