Is it true that Cockney English is disappearing? And being replaced with "Jafaican"?

I read a couple of comments to that effect on this Youtube video, which is basically a man ranting in Cockney from the movie Football Factory (2004). The comments bemoan American ignorance about the actual frequency of Cockney speakers, and suggest that it's all but disappeared amongst the working class except in a few areas. Saddening, if true. Is it? (I'm not looking for a thesis, just "man-on-the-street" type opinions.)


Solution 1:

The following link probably tells more about Scouse than most people want to know:
