it is extremely dependent on a lot of things. some companies are much much better at economically pushing their systems and software.
a lot of people are a bit naive in thinking about this sort of thing by considering stricly things like market share.
for an example, the Nintendo Gamecube sold 20 some million and the PS2 like 150 million systems. YET Nintendo made MORE in that generation than Sony did during the same period of time in their video game division
sales are useless if you're putting in tons of development costs, over marketing, selling at a loss to begin with and not recouping enough revenue in software sales
I voted 20 million for the simple fact that every single system that has sold over 20 million system (bar maybe the Xbox's because Microsoft is crazy and shells ridiculous amount of money to make their video game division work) has profited for the company
