your ps4 predictions are not bad
you mostly underestimate xb1 and overestimate wiiu

what are your July numbers?
give them and ill try to fix them :D

For XBO, i think i only super underestimate Januray and April, because February and June was very unexpect month for some user, not only, my June and February prediction was all considering above the average.

For Wii U. yes, i'm a fucking fanboy of crap and i always overestimate it's prediction BHUHAHAHAHA!!!!!!!!!!!!!!

July prediction:

[PS4] 195,000
[XB1] 165,000
[3DS] 95,000
[WIU] 50,000

so the NPD results will be something like this :D

PS4: 187k - 216k
XB1: 173 - 182k
WiiU: 40-45k

And what about 3DS? ^^

sorry, but i don't really care about handhelds :P

and there is only one handheld on the market*. it is boring.
3ds beats 3ds sales form last year. 3ds lost vs 3ds last month sales.
where in the fun and drama? :D

*yes, ps vita is dead :(

Sadly, yes.

The last numbers are 6 months old... :-/
