PSP comparisons: After 221 weeks, PSP is where PS2 was at 172.6 weeks (June 19, 2003), where DS was at 97.7 weeks (October 13, 2006), and where GBA was at 149.0 weeks (January 25, 2004).
X360 comparisons: After 169 weeks, X360 is where GCN was at 16.3 weeks (January 1, 2002), where PS3 was at 33.1 weeks (June 25, 2007), and where Wii was at 4.9 weeks (December 30, 2006).
Note that X360 has now made it out of GameCube's first calendar year. Of course, where that precise point goes is impossible to say since we just have numbers from several days on either side of that year switch, buuuut for our purposes it's now.
PS3 comparisons: After 121 weeks, PS3 is where PS2 was at 36.1 weeks (November 6, 2000), where PSP was at 59.9 weeks (January 28, 2006), where GCN was at 119.4 weeks (December 24, 2003), and where Wii was at 31.8 weeks (July 7, 2007).
Last week PS3 was at 34.4 PS2 weeks, so it just moved forward by 1.7. This is one of the few times it's gone forward more than one PS2 week at a time, helped both by a Yakuza 3 bump and the PS2 shortages of late 2000.
Wii comparisons: After 118 weeks, Wii is where GBA was at 93.9 weeks (January 5, 2003), where DS was at 75.7 weeks (May 10, 2006), where PS2 was at 112.6 weeks (April 25, 2002), and where PSP was at 163.0 weeks (January 20, 2008).
DSi comparisons: After 18 weeks, DSi is where GBASP was at 37.9 weeks (November 2, 2003) and where DSL was at 12.5 weeks (May 25, 2006).

DS vs PSP: Weekly shares of 42.1 / 57.9 bring total shares to 68.7 / 31.3. This is the first time PSP has outsold DS since the release of the DSi. At this week's rates, PSP catches up to DS in 869.6 weeks (November 7, 2025). If DS stopped selling and PSP continued at this week's rate, it would catch up in 236.9 weeks (September 22, 2013).
X360 vs PS3: Weekly shares of 27.3 / 72.7 bring total shares to 24.8 / 75.2. If PS3 stopped selling and X360 continued at this week's rate, it would catch up in 129.3 weeks (August 31, 2011).
PS3 vs Wii: Weekly shares of 70.6 / 29.4 bring total shares to 27.0 / 73.0. This is the first time PS3's weekly share has been over 70%. At this week's rates PS3 catches up to Wii in 211.4 weeks (March 28, 2013). If Wii stopped selling and PS3 continued at this week's rate, it would catch up in 123.5 weeks (July 21, 2011).
Week over week, PSP is way up, X360/PS3 are a little up, and PS2/DS/Wii are a little down.
Through the first ten weeks of the year, almost everything is down by some degree. Here's how the year-to-date year-over-year percents stand as of now.
Home hardware: -42.2%
Portable hardware: -21.6%
Sum of all hardware: -30.7%
At 16,560, Wii has its worst week yet, beating its previous low of two weeks ago. The past three weeks are the only times Wii has been below 20K (in MC, anyway).
Famitsu Software Stuff
A very strange week on the Famitsu Software Pie. Usually DS sits in first place with a comfortable margin at the top. This week thanks to Yakuza 3, PS3 beats it. The last time PS3 sat on top was the week of Metal Gear Solid 4. On the other hand, X360 usually sits at the bottom, but thanks to continuing Star Ocean 4 performance and three new games in this week's Top 30, it's PlayStation 2 which for the first time is the lowest ranked among the systems that aren't lumped into "Other".
Yakuza 3 (3445) is off to the biggest start the series has yet had. It's also one of the biggest Sega openings of the last decade in general. Among all their games as a third party, I only see two higher first weeks: Love & Berry's 425K first week in 2006 on DS, and VF4's almost-identical-to-Y3 357K in 2002 on PS2.
Mario & Luigi RPG 3 (3432) shows some surprising legs. Even with it being a far-from-holiday release as I've previously pointed out, its third week (56K) is bigger than the third week of either the original (25K) or the sequel (29K). Though it should be noted that the original didn't have its best week until its sixth week in late December (73K).
