Why does Pioneer want to stop making plasmas?

Both Samsung and Sony have already shown off prototypes, and we'll hopefully see some real world examples within the next couple of years.

When an LED is off, it really is off, giving you truly, deep dark blacks, banishing the dishwater greys of old. Team that with the improved colour fidelity that true blacks give you and you start to eliminate many of the benefits that plasma is supposed to offer over its arch-rival.
