So basically Nintendo has release a ton of re-releases, Sony's downloadable content costs a bit more (due to there being a bunch of full games instead of small ones) and they are building the PSN Store up faster then Microsoft did Live (apparently), and Microsoft has the biggest load of content.

It seems to be all pretty interesting.

 Well right now Sony vs Nintend, Sony has more original titles, Nintendo has the most re-releases. Take your pic. Sony is also gaining quite a few more games by the end of the year (I think SOCOM is still coming this year)
