Who knows what they will really do, but it kind of makes sense to bump the specs. Updated lightning is a no brainer. Apple wants to get past this connector fragmentation ASAP. UK supports seems a safe bet as well. Surface is just in pre-release and a A6 spec bump, IGZO panel, and thinner body could present serious problems for it before it even gets started. And lets not forget the Nexus 10 is right around the corner. Nook, Android, Surface, they were all designed to try and compete Apple's latest and greatest, the new iPad. And then right as they come to market, Apple drops a new thinner, faster iPad with significantly better battery life. Sounds like a helluva shrewd move. Thinking about it, the lightning connector has another advantage, if Apples competitors got wind of an upgrade, Apple could put it out there that they were just updating the connector, keeping the competition focused on the new iPads older specs! Machiavellian!
The thing that really gets me though, is how we are trained to think we have to have the latest model of whatever toy has our fixation. So you just bought a 3 and now there is a 3S. So? Your processor didn't slow down, its still the same iPad you just bought, and you can probably get several more years out of it. My 3 year old is still rockin' on my original iPad even after dousing it with water twice, and spilling milk all over it at least once. Apple should upgrade when the new tech becomes cost effective to use or when it makes sense to do so competitively. Don't make as wait.
