Let's face it: for now (and who knows how long) the only Large format Pearl eink reader will be Kindle DX. Amazon haters will either have to wait indefinitely or go with the PB902/903.

There's money to be made even without Pearl.
More seriously: holding back new designs for lack of Pearl is conceding the market to Amazon without firing a shot. Might as well pack up the bags and go home if you're going to do that.
Competitors compete. Losers whine.
Pocketbook is competing and not whining.
Let's wait until the readers ship to see how they stack up in real world use.
