Pretty much, whilst I don't know Nintendo's current standing since 3ds launched, I just took a look back at the old chart, and from the last update we have,

2008-2011:

• Microsoft's EED profited 2.598 Billion
• Sony's Divison lost 1.045 Billion
• Nintendo's Division profited ~13. 3 Billion

This is off course old data, and given recent events, I don't see things going up for Sony, and I see things going down for Nintendo, for various reasons, including R&D, console/handheld launches & nature disasters. As for Microsoft, realistically, I think their next sales update could be their biggest profit since the Xbox brand launched (obviously 2001-2007 was all losses)

update

WW360 DEC 10TH- 851,678

WWPS3 DEC 10TH- 704,669

Difference: +147,009 for Xbox 360

WW360 DEC 17thTH- 766,126

WWPS3 DEC 17TH- 343,886

Difference: +422,240 for Xbox 360

Edited.

WW for the 20th is not up yet, so your gap numbers are a little fudged..

I assume by Dec 20th you mean week ending 12/17 which had numbers just start going up on the 20th. Those numbers are not complete yet. So the difference in 360 favor will shrink. Also believe adjustments for November arent included in your figures. Those increased PS3 lead by about 150K. It is looking like the PS3 will be ahead by about 525K as of Dec 17th.

My bad I meant 17th instead of 20th. Of course everything is a rough estimation. Even with ~52k in the PS3's lead it is going to be a close race this year. One console did solidly strong the first half of the year and the other is breaking records the second half of the year.

Just a note to be added. PS3 is undertracked 50k just in the U.S.A. (Basing on NPD November numbers) and the Wii is overtracked by 150k just in the U.S.A. (again just basing on NPD November numbers) I know I have no "real" figures for this but considering and looking at the deals (for hardware) and software in Europe (GFK) PS3 and 360 both look underestimated the PS3 more so. So I don't think it's exactly safe to call any console "the best selling console of 2011" untill there aren't proper adjustments made. I will try to find sources for Europe hardware sales though.

I think the PS3 will end up winning in 2011, but not by much, and 360 will have some good momentum going into 2012.

525k is going to be a tough number to pull and on top of that 50k another 50k needs to be added on (just for the U.S.A.) as I have calculated the November VGC and November NPD numbers just for the PS3. As Xbox 360 sales are perfectly in line with media crate and NPD.

November NPD: 900K

VGC November 2011 4 week sales: 850k (Nov-5th-Nov-26th)

Adjustments based on the November NPD have already been made.  Read this thread they are discussed.
