How quickly things can change in the gaming industry.

Sony, which had been riding a bumpy road of bad press, negative reviews and disappointing developments, pulled a coup of sorts this week at the 2007 Game Developer Conference. Sony impressed gamers yesterday during its keynote with its announcement of PlayStation Home and its preview of a loveable new PS3 title called LittleBigPlanet from independent developer Media Molecule. Suddenly, Sony had a good buzz going again.

Meanwhile, Nintendo's keynote today fizzled, despite the presence of Shigeru Miyamoto, one of the true luminaries of gaming. Nintendo didn't really have any announcements this morning, no breaking news and no real earth-shattering innovations or developments. Worse, the new console's Miis look positively ancient comared to the new PlayStation Home that Sony debuted yesterday. And perhaps worst of all, the library of Wii games coming this year doesn't look all that impressive outside Super Mario Galaxy (Metroid has apparently been pushed off again).

Is Sony really on the comeback trail? Is Nintendo and the Wii losing its luster? Time will tell.
