iPad 3 release this September? Not going to happen! If it does I will eat my Smart Cover.
With some fava beans and a nice Chianti?
As we speak, thousands of Apple engineers, programmers, marketers, designers, and logistics and purchasing weasels are toiling away on future iterations of iPhones, iPods, iPads, MacBooks, and probably a couple of gizmos we haven't even thought of yet.
Its pretty safe to say, however, that there will NOT be a release of an "iPad 3" this fall. It simply doesn't make sense, it doesn't fit into any coherent product planning schedule. And more importantly, it fails to take into account the established pace of processor development.
In very general terms, it ONLY makes sense to introduce an updated hardware platform when core processor, GPU, or memory chip design and fab have advanced enough to make it worthwhile. And that (again, speaking in fairly general terms) takes about a year. Not just due to the design process, but because its simply not profitable to set up a chip foundry for only six months worth of production. (The first month is spent working out bugs and getting the defect rate down to acceptable levels.)
There are many, many things to worry about: Mass extinctions, global warming, antibiotic-resistant bacteria, and another season of "American Idol" seem like a good place to start. But "worrying" about an iPad 3? No chance.
