From a development perspective they have complimented the PS3 on various occasions. With regard to marketing Sony made some mistakes and deserved some criticism. IMO it's good that they state their criticism openly where justified, I think it adds credit to their positive remarks regarding the hardware.
XBox 360 game developers, often seem censored, retracting statements or sometimes spread misinformative propaganda (for example Epic, with regard to Gears).
