Famitsu didn't update at the regular time this week, so just a Media Create update this time.
Based on the latest Media Create hardware numbers...
DS vs PSP: Weekly shares of 51.6 / 48.4 bring total shares to 68.4 / 31.6. If DS stopped selling and PSP continued at this week's rate, it would catch up in 343.8 weeks (November 28, 2015).
X360 vs PS3: Weekly shares of 23.1 / 76.9 bring total shares to 24.6 / 75.4. If PS3 stopped selling and X360 continued at this week's rate, it would catch up in 297.3 weeks (January 7, 2015).
PS3 vs Wii: Weekly shares of 55.9 / 44.1 bring total shares to 28.1 / 71.9. This is the first time PS3 has outsold Wii nine weeks in a row. At this week's rates PS3 catches up to Wii in 984.5 weeks (March 9, 2028). If Wii stopped selling and PS3 continued at this week's rate, it would catch up in 207.1 weeks (April 15, 2013).
Week over week, PS3 comes back down to Earth, Wii has a mini monster bump, and everything else stays pretty flat.
Through the first seventeen 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.
