are they reliable

VGC is spot-on on both the 360 and Wii, ps3 seems undertracked by 10-20k

well VGC does an exellent job

They are from GfK, you cannot get any more reliable than that. GfK is Germany's NPD, like Japan's Media Create, UK's Chart-Track etc.

Well thats not a bad performance at all ... it may actually be able to take the lead over there this holiday :)

Yes, VGCharts LTD is pretty close, although they include 2/3 weeks from November not included in the GfK data. So PS3 is a little low, Wii maybe a little high, and 360 maybe very slightly high, but all in quite acurate, and nothing is majorly different.

Your August+September numbers actually also include the October numbers. Nice to see ioi is so close to GfK.

@BKK:

August + September:

Wii - 97,000
PS3 - 72,500
360 - 47,000

Thats not right! In End of July the LTD for Wii, PS3 and 360 were:

Wii - 291.000
Xbox 360 - 281.000
PS3 - 99.500

The LTD for the End of October are:

Wii - 389.000
Xbox 360 - 328.000
PS3 - 172.000

As you can see the numbers above fits (almost) perfectly. So its not September + August, but August - October. (so all three months together).

Here is an analysis/ some stats of myself for the data:

Sales October:

Playstation 3 - 37.000
Nintendo Wii - 28.000
Xbox 360 - 12.000

Market Share October:

Playstation 3 - 48 %
Nintendo Wii - 36,4 %
Xbox 360 - 15,6 %

LTD End of July :
Nintendo Wii - 291.000
Xbox 360 - 281.000
Playstation 3- 99.500

LTD End of October:
Nintendo Wii - 389.000
Xbox 360 - 328.000
Playstation 3 - 172.000

Sales-changes from August - October (3 Months) :

Nintendo Wii - 98.000 (average of ca. 33.000 per month)
Playstation 3 - 72.500 (average of ca. 24.000 per month)
Xbox 360 - 47.000 (average of ca. 16.000 per month)

Market share End of October: (Comparsion to Market share End of July)

Nintendo Wii - 43,8 % (+ 0,5%)
Xbox 360 - 36,9 % (- 5,0 %)
Playstation 3 - 19,3 % (+ 4,5 %)

If the Playstation 3 continue to sell 25.500 (like August - October) Units more in 3 months than the Xbox 360, it will overtake the Xbox 360 in 18-19 months.

Should the PS3 continue to sell 25.000 (like in October) more per month than the Xbox 360, it will obertake the Xbox 360 in circa 6 months.

As you can see, the PS3 could only sell 25.500 more Units than the Xbox 360 in this three months - but in the last (October) alone it sold 25.000 units more than the xbox 360 - so in August and Septembre (Price cut & Halo 3) the sales were balanced between PS3 & 360.

Some more stats: 

Xbox 360 - 328.000 units in 23. months (14.200 in average per month)

Nintendo Wii - 389.000 units in 11 months (35.360 in average per month)

PS3 -  172.000 units in 8 months (21.500 in average per month)
