As flash cost drop, so do product costs and ultimately, so will EDIG's piece of the pie per product...however, as you note, a greater variety of products could emerge....but what is EDIG to do, spend it's resources on chasing every new product known to man in the courts?
At some point EDIG should have its payday and be very pleased that its patent portfolio pegged such a huge market.
Then they will be faced with what PTSC announced today, focusing on M&A.
