When you create something to meet a certain price point you will always have to make sacrifices in what is put into that product. In this case I think it was rightly decided to have 4 inputs and 1 output as that is what most of the market needs. There are other higher end options in pre pro's that will give you more inputs and outputs at a price increase I am sure. I would imagine no more than 20% of the people who purchase the 997 will have more than one display. It seems like a bad financial decision to make everyone pay more for something only 20% of the market will use.
