Where I come from the situation is totally different. Most employees go on and on about MS and the 360 and bashes the PS3 and Sony. This was even worse when the PS3 was that "expensive" console with "no games" and "bad versions" of multiplats..
And let's not forget he o'holy LIVE service...
Please stop talking about Microsoft 'bribing' companies, Sony's done exactly the same thing in the past, present and will do so in to the future. Sony's marketing money and securing exclusives helped bury Sega and almost Nintendo too.
You are right to some extent. Sony pushed disc space in both PS1 and PS2 era with CDs and DVDs compared to cartridges and some other CD based formats. Developers liked this, saw the possibilities and many made the jump. Also, Nintendo was famous for shitty 3rd party treatment. This gen Sony continues pushing formats AND are not treating 3rd parties like shit. There is no reason for devs to jump from Sony platform, besides easier development on the 360 (for some devs).
