Welcome to the forum.
Lots of good info and people on this forum; but the rumors of when the iPad comes out, and the facts when they are finally announced will be pretty much the same here as any other news or blog site. This is not Apple leak central.
Then again, there are usually at least a few threads going where people can discuss and expand on those rumors. Me, I prefer to wait and see what actually happens, but I understand the urge to speculate and dream. Apple's product announcements are just a bit like Christmas, several times a year.
Stick around for a while. I'm sure you'll like the place.
