Acutally, Perez mentioned this about 2 months ago and it was brought up here on APUG, but was dismissed then as improbably due to their announced strategy. Basically, what Perez wants is a move to the high end, high capacity printers for POD shops. The problem is that the ink set for these high end printers is not all that good. They have a high degree of metamerism and thus the prints shift color with illuminant.
If they don't fix that, they are going to fail in their last line of business in the digital side.
