@NJ5 However, in an alternate universe where all three consoles had launched at the same time, market share increasing would imply increased weekly market share, which would imply good sales. Due to the year head-start by the 360, however, increasing market share doesn't necessarily mean increasing weekly sales, as per your formulation.

Mathematically, you can consider that as a sub-case of different launch times, and vice-versa too, by assuming the launch time as being the launch time of the first console to be launched. This means there's really no difference between different or equal launch times.

Just imagine that the Wii and the PS3 sold 0 consoles per week in the first year, and then started selling. So increasing market share still doesn't imply increasing weekly sales. For example, they sell a lot at launch (but not enough to overcome the top console) and sales then decrease, but market share is always increasing as the consoles find their space in the market. It's all about average sales.
