Deep Ocean Expeditions dives to the Titanic

I'm curious if anyone here has visited the Titanic wreck via Deep ocean Expeditions:

A good friend paid to make the dive to the Titanic 3 times, and Bismark twice. I may be able to afford this route at current prices within 5 years. I suspect with improvements in technology, Titanic dives will become more accessable. Some friends feel 2012 is it- after the centenary, Titanic dives will cease forever- That will happen when interest in the Titanic vanishes- which will never happen
