Based on the latest Famitsu hardware numbers...
PSP comparisons: After 220 weeks, PSP is where PS2 was at 171.7 weeks (June 13, 2003), where DS was at 97.4 weeks (October 11, 2006), and where GBA was at 148.3 weeks (January 20, 2004).
X360 comparisons: After 168 weeks, X360 is where GCN was at 16.2 weeks (December 31, 2001), where PS3 was at 31.8 weeks (June 15, 2007), and where Wii was at 4.8 weeks (December 30, 2006).
PS3 comparisons: After 120 weeks, PS3 is where PS2 was at 34.4 weeks (October 25, 2000), where PSP was at 58.8 weeks (January 20, 2006), where GCN was at 119.1 weeks (December 22, 2003), and where Wii was at 31.3 weeks (July 3, 2007).
PS3 and GCN streams have crossed again, for what should be the next-to-last time. GCN numbers were pretty poor from much past this point, so the next time PS3 gets ahead it should be for good.
Wii comparisons: After 117 weeks, Wii is where GBA was at 93.9 weeks (January 4, 2003), where DS was at 75.5 weeks (May 10, 2006), where PS2 was at 112.3 weeks (April 23, 2002), and where PSP was at 162.7 weeks (January 18, 2008).
DSi comparisons: After 17 weeks, DSi is where GBASP was at 36.0 weeks (October 19, 2003), and where DSL was at 12.4 weeks (May 24, 2006).
At this point early-DSL is pretty clearly pulling away from early-DSi.

DS vs PSP: Weekly shares of 57.2 / 42.8 bring total shares to 68.8 / 31.2. If DS stopped selling and PSP continued at this week's rate, it would catch up in 397.0 weeks (October 9, 2016).
X360 vs PS3: Weekly shares of 24.4 / 75.6 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 162.3 weeks (April 11, 2012).
PS3 vs Wii: Weekly shares of 67.1 / 32.9 bring total shares to 26.8 / 73.2. This is the highest weekly share PS3 has had versus Wii since Wii launched, though it has been over 60% on three previous occasions. At this week's rates PS3 catches up to Wii in 265.3 weeks (April 2, 2014). If Wii stopped selling and PS3 continued at this week's rate, it would catch up in 135.4 weeks (October 5, 2011).
Week over week, PS3 has a bump and X360 returns from one. The rest don't share any common movement.
Through the first nine 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: -44.0%
Portable hardware: -23.1%
Sum of all hardware: -32.3%

Star Ocean 4: The Last Hope has a start that is greater than the recent PSP remakes of 1 and 2 (2761 and 2849), but far below that of Star Ocean 3 (1567).
It's pretty understandable given that it's an X360 game, though, and in THAT context, it's started out much more quickly than any of that system's other big games. In fact, this first week makes it the #2 X360 game overall.
The PSP Idolmaster games are off to a big start, too; bigger than any of the earlier X360 releases. Even adding up the original and its budget rerelease (2644 and 2752), no X360 version of the game has yet hit 100K.
Without a holiday behind it Mario & Luigi RPG 3 (3432) doesn't maintain its large lead over Partners in Time (212). However, at 2 weeks it's still about where Partners in Time was at 3 weeks.
