Surely the impact is watered down with every sinlge day that passes... it has to be, thats obvious.

The question was how much of a system seller it will be... hardly any of the people saying it will be huge have coupled that with a number. Huge is relative and subjective.

Lets see some number fellas.. Increase on sales week1 and through week4?

OK I'll bite

Week 1: 600K

Week 2: 400K

Week 3: 350K

Week 4: 300K

So In my opinion iw will be a huge system seller
