According to Next Generation:

Some in the industry have taken this as a lead to speculate that September 16 would be a launch date in Japan (a Saturday before a national holiday) followed by September 21 in the U.S. These dates are not confirmed and, as always, launch dates are subject to constant revision.

I don’t think anyone is surprised by this since there were no signs of Sony releasing it’s console on March. Could this be good news for Microsoft? In a way yes, but in another, no.

Sony hasn’t explained the reason of the delay however Next Generation claims that they will be providing a service named “HUB” that will feature the same things as XBox Live and also sell music and videos. If Sony accomplishes this well not only will they be threatening the XBox but they will also threatening to steal some of iTunes’ market share.

After hearing about HUB I’m thankful that Sony isn’t releasing the console in March.
