I don't believe this at all. MS will never let Nintendo have a 2 year lead with the Wii 2, so they will probably go for the late 2013 holiday season.
I don't know about Sony, but if they do go for late 2014, they are really gonna take it hard up the backside this time with both Nintendo and MS getting a huge headstart. So I think sony will probably go for early 2014 or late 2013 as well.
