Now that's a real statement! However, it seems that I've heard variations on that before, like just before the introduction of every new product that Apple makes. It's a hope expressed by many but it seems never to be fully realized. The thing is, Apple's profit margins are remarkable consistent year-by-year and product-by-product (with a few, low volume exceptions, like the original Apple TV). So, you seem to be proposing that Apple is finally going to turn another leaf and undercut their profits to keep market share. I doubt it.I accept your challenge. They wont have to compensate. If Apple sticks in the better display and dual core ARM9 ect. they will still make a little (probably much less) money off of it, but still get a little. This is a price cut they may be willing to take if it means keeping them on top of the tablet market for years to come.
I'd say that the most likely scenario is that the base price on the iPad will go up if Apple adds both a Retina display and a dual-core ARM9 with improved graphics and more memory. Maybe they will keep the current 16GB, WiFi-only iPad as their low-cost alternative. That wouldn't be a bad option since I suspect that the current iPad could still sell in good numbers for some months to come (i.e. well into 2011).
