"At the end of [2011], the digital business is bigger than the packaged goods business, full stop. No questions in my mind. Then, you know, I think that we’ll find ways to even sell our packaged goods content in chunks and in pieces and subscriptions and micro-transactions,"
Just a snippet, more at source if you're interested.

It isn't that retail is going down, it really is that digitial distribution is coming up. It really makes me wonder how accurate this site really is given that as digital revenue increases our numbers here may not reflect the whole reality.
It also shows that Nintendo seems to be a little behind the times with their business model. If they don't catch up they may be beat in the same way that they got beat with the N64, not adapting to new distribution realities in time no matter their other incumbant advantages and natural first party talent.
Other than that, PSN / Xbox Live are a much of a muchness aside from the fact that the latter is a better store than the former and thus achieves much higher revenue per user. Though most of this aint console, I would say what this effectively means is that PC / Mobile are the same size as home console and handheld consoles combined as at the middle of 2011 which means that the previous trend of games being sold more on consoles is reversing back to other platforms.
So given this fact, I would say in order of revenue, though PC is multiple platforms combined through 2011:
Console and PC:
PC
Wii
360
PS3
Handheld:
DS
iOS
3DS
Android
PSP
Windows Phone 7
Tease.
