1. gvs total=671, last quarter total=320 ==> ps4 & xb1 revenue ~=400M
2. total revenue = 1461M, including 19M from last quarter write down, total margin 36% ==> the real margin ~=35%
3. Use last quarter margin rate for this quarter's non console margin rate, which is 40%
4. Let console margin be x, we have 400x + 1061*0.4 = 1461*0.35, answer: x= 0.2173 ==> console margin rate is about 22%.
it would be safe to say the real margin is something between 20% to 25%.
