One thing which needs to be considered is how the differences between the development budgets and timelines for Wii and HD consoles will impact the generation.
Wii development is cited to be between 1/4 and 1/2 of the cost of PS3 and XBox 360 development which is partially due to smaller development teams, and is also due to shorter development times. Wii development is similar to previous generation games which (for big budget games) had development teams of 40 to 60 people working 12 to 18 months (for the most part); in contrast many of the big budget PS3 and XBox 360 titles have had development teams of over 100 people, and have taken 24 to 36 months to complete.
What this means is that a similar investment from publishers in Wii projects will end up producing 2 to 4 times as many games of a similar scale and quality as it would if invested in PS3 and XBox 360 projects. In other words 'This generation is not like the previous generations because a minor shift in publishers towards the Wii will result in a massive shift in library size and quality' ...
