I think one of the factors at play is how people can rank the consoles in their minds if all three cost the same amount.
You can be:
| 1 | 2 | 3 | 4 | 5 | 6 | |
| 1st Choice | Wii | Wii | X360 | X360 | PS3 | PS3 |
| 2nd Choice | X360 | PS3 | PS3 | Wii | X360 | Wii |
| 3rd Choice | PS3 | X360 | Wii | PS3 | Wii | X360 |
You can get an Xbox 360 for $200-$400, Wii for $250, or PS3 for $400 essentially. But I think its fair to say that alot of people only have a slight preference one way in favor of PS3 or 360. Given that the Xbox 360 is selling for $268 (per Gamasutra) in the USA, scenarios 1-4 are likely the most common, probably to 70-80% of the market. Price drops when PS3 is immediately beneath Xbox 360 will change some minds to PS3 but, when Xbox 360 is beneath PS3 in preference, and gets a price drop it probably changes more minds since it is cheaper already and offers comparable experiences. Wii outsells Xbox 360 2:1 or more in most markets even when 360 is within 10% by average price or cheaper so Xbox 360 price cuts would only switch some people in scenarions 1 and 6 toward Wii because it is sufficiently differentiated.
So...in terms of weighting and how purchasing patterns in the six groups could go:
| 30m | 25m | 20m | 15m | 10m | 5m | |
| 1 | 2 | 3 | 4 | 5 | 6 | |
| 1st Choice | Wii - 60% | Wii - 60% | X360 - 50% | X360 - 50% | PS3 - 45% | PS3 - 45% |
| 2nd Choice | X360 - 30% | PS3 - 30% | PS3 - 35% | Wii - 35% | X360 - 35% | Wii - 35% |
| 3rd Choice | PS3 - 10% | X360 - 10% | Wii - 15% | PS3 - 15% | Wii - 20% | X360 - 20% |
|
Wii |
18m | 15m | 3m | 5.25m | 2m | 1.75m | 45m |
| X360 | 9m | 2.5m | 10m | 7.5m | 3.5m | 1m | 33.5m |
| PS3 | 3m | 7.5m | 7m | 2.25m | 4.5m | 2.25m | 26.5m |
Thats very rough, but it would be 45m Wiis, 33.5m 360s, and 26.5m PS3s based on preferences of the six groups. I'd wager Wii will finish a bit higher and the others a bit lower but its not a bad guess off the top of my head.
