I think I have the answer.
It's a simple mathematical equation.
Basically...
PS3 * Revolution * Xbox - 360
We just have to find out the numeric values for ps, revolution and xbox.
A revolution is one turn. Therefore in radians it is 2pi.
ps3 can determined by finding ps2. Dividing that by 2 so you can find out what ps is and then multiply that by 3.
But honestly.... staying on topic.
I personally like the Revolution. The DS has shown me that Nintendo knows how to innovate.
Like this....
PS2 = 149.99
ps2/2 = 149.99/2
149.99/2 = ps
74.995 = ps
Xbox turns out to be 179.99 (my numbers could be incorrect.)
So we plug all our numbers into the orginal equation like this.
(74.99500 * 3 * 2 * pi * 179.99)
And we get the answer of 254 437.904
Or to the correct sig digs,
2.54x 10^5
