You're misinformed and there's no evidence of this, Apple would like everybody upgrade every year. Therefore you're making stuff up because you think it's real.
What's more logical to you:
1. Spending $500-$830 every year to receive a marginal upgrade in functionality.
2. Spending $500-$830 every two years to receive a beneficial upgrade in functionality.
This forum is not the real world. In the real world, people buy their discounted iPhone 4's, sign two-year AT&T contracts, don't regret missing the iPhone 4S, and look forward to the iPhone 5. In the real world, no one buys a $700 iPad in 2010 and runs out and plunks down another $700 a year later. Mobile devices, New Every Two, been going on since 1998.

I don't think they're making iPads for a "new every two" like they do with iPhones.
iPads are like computers or like MBPs and MBs were a few years ago. They get spec bumps and design changes every year. Apple wasn't expecting people to upgrade their computer every two years though. They were just improving the platform, mainly hoping for more NEW customers to buy one. Sure, upgraders are good for Apple but new customers adopting the iPad are even better. An example of Apple's goals is the Mac vs PC campaign. That was used to draw PC users to the Mac, not get Mac users to upgrade their computers.
Apple certainly can't take a year off, go two years between device releases, as that would make them uncompetitive.
What we're talking here is the target audience, the bulk of the consumers interested in Device X. When it comes to the The New iPad:
iPad 1 Upgraders: About 70% of the opportunity.
Virgin iPad Buyers: About 28% of the opportunity.
iPad 2 Upgraders: About 2% of the opportunity.
And the only reason the iPad 2 upgrade group is that large is because of the retina display which is a substantial improvement to the low-res image they're accustomed to and the hi-res image they've grown to love on their iPhone 4's.
