Let's see, I like the 6500.   The numbers in the Atari line had 4 digits (2600, 5200, 7800) unless they were computers (400, 600, 800)

I do notice that the console had even-ish numbers that you could divide by 2 and get a clean number (5200/2=2600.   7800/2=3900.

6500/2 = 3950... kinda need that double zero at the end.

So I would just make it 6600 /2=3300.

People in the bible belt would go off on how it is too close to 666 and a "evil union of the 5200 and 7800", you get all that free publicity, sales soar, win win! 

As much as I think there should be a 6900....Well, every time a new console is released, they just add 2600 to it (Like 5200 + 2600 = 7800)...So if this new console came out, it'd have to be a 10,400.   Just kinda rolls off the tongue, no?

You'd probably get something with extemely painline controllers which will bruise your fingers and a beer compartment because you spent money on something that will cause you to regret and the only way is to drown your sorrows.
