Apple will once again march to the beat of its own drummer, as the Apple WorldWide Developer’s Conference keynote address with Apple CEO, Steve Jobs, will be going on at the same time as Microsoft’s E3 press conference. It will be impossible to be in two places at the same time, and we suspect that Apple knows this.

Apple is expected to announce the next version of OS X called Lion, in addition to iOS 5, which are expected to be the two big draws. In addition, Apple is rumored to be taking the wraps off its new cloud services offerings, which could present some interesting surprises.

The news really isn’t that shocking, as Apple had already confirmed that they would be holding the WWDC keynote during E3 week some time back around March, if we recall correctly. Of course, Apple has done this type of thing before, and normally the company does not worry about potential conflicts with other things going on around it.
