Based on the latest Famitsu numbers...
PS3 comparisons: After 87 weeks, PS3 is where PS2 was at 19.7 weeks (July 14, 2000), where PSP was at 52.2 weeks (December 5, 2005), where GCN was at 93.4 weeks (June 24, 2003), and where Wii was at 21.9 weeks (April 28, 2007).
Wii comparisons: After 84 weeks, Wii is where GBA was at 86.5 weeks (November 13, 2002), where DS was at 68.2 weeks (March 20, 2006), where PS2 was at 96.0 weeks (December 30, 2001), and where PSP was at 147.5 weeks (October 3, 2007).
Based on the latest Media Create numbers...
DS vs PSP: Weekly shares of 46.0 / 54.0 bring total shares to 69.9 / 30.1. At this week's rates, PSP catches up to DS in 1540.7 weeks (January 22, 2038). If DS stopped selling and PSP continued at this week's rate, it would catch up in 228.6 weeks (November 30, 2012).
PS3 vs Wii: Weekly shares of 23.0 / 77.0 bring total shares to 25.7 / 74.3. If Wii stopped selling and PS3 continued at this week's rate, it would catch up in 335.7 weeks (December 19, 2014).
A few weeks back I mentioned that it was hard to try to compare MGS4's bump/spike to a previous PS3 event, since the only big thing that wasn't also influenced by hardware SKUs and holidays was Gundabump. Now that we've got a few weeks to go with, I was curious whether they behaved at all similarly.
Not really, it seems. MGS4's spike and drop was much quicker.
I was also wondering about how Wii is performing compared to PS2. We can all see the weekly update on how Wii at X weeks is like PS2 at Y weeks, but I want to see more of a weekly look. Not that Wii's 40-50K weeks are bad, but they're not as impressive as what it was doing last year. How does
that compare to PS2? Unfortunately with them launching at different times of year there's not a perfect way to set up a weekly comparison, so I've got three flavors. In all cases Famitsu is used since the PS2 data goes back far enough, and I've capped the charts at 300K to give a better view of the less gigantic weeks.
First, launches aligned. Thus you can see the big holiday peaks don't match up. Hard to compare recent Wii performance with "recent" PS2 performance, since it was in holiday mode.
Second, dates aligned with PS2's 2000 matched to Wii's 2006. PS2's holiday 2001 and Wii's holiday 2007 match up pretty well. However, Wii has more of a post holiday lull. PS2 comes down to Wii levels, but right near the end there it looks like PS2 spikes again. There wasn't a single big PS2 game
that week; in fact, Super Mario Sunshine was #1. There were 5 new PS2 games in the Top 10, though, so maybe it was the sum of bumps from different audiences?
Third, dates aligned with PS2's 2001 matched to Wii's 2006. Other than Wii spiking a bit higher in holiday 2007 versus PS2's holiday 2002, this seems a pretty close match through most of Wii's life, with little trends and bumps frequently changing which is ahead.
EDIT: Actually, I made a mistake. I wanted one where PS2 launched first, and one where Wii launched first. That the PS2 2001 / Wii 2006 one matches so well is just weird serendipity. I wonder if that will continue? Anyway, here's what I SHOULD'VE done:
Fourth, dates aligned with PS2's 1999 matched to Wii's 2006. In this case past PS2 launch Wii is pretty consistently matching/exceeding what PS2 does until the bump and bump-within-a-bump of Final Fantasy X at the end.
