Apple is revving up its marketing machines for its upcoming Worldwide Developers Conference (WWDC), stating that it will move the Mac OS X Leopard and OS X iPhone development platforms into the spotlight.

It isn’t an especially surprising and spectacular announcement, but it provides a clear picture of what Apple tried to tell us with a "two bridges" announcement a few weeks ago.

Apple did not mention any new products that could be introduced at WWDC, but we are surely not the only ones hoping that there will be a 3G iPhone and, since this is a product most of us are expecting anyway, at least one surprise. Apple would not be Apple, if there wasn’t at least one surprise, right?
