Unless you have some hard facts to back up that statement, I would say it is just your opinion, and not an accurate one. I suspect that large publishing houses own the rights to so many books, and will so for so many decades to come, that they will not be going anywhere anytime soon. I do expect the market to slowly change over time to where more and more independent authors publish their own books via electronic means and thus circumvent the large publishing houses. I certainly hope they do.
