Prices for old iPads drop $50 as Apple gears up for launch of iPad 3 - but could the new HD tablet be more expensive?

American retailer Best Buy dropped the price of iPad 2 models by $50 this weekend - a move that tech insiders see as confirmation that a new model of Apple's best-selling tablet is just around the corner.
Analysts and technology sites expect a launch in early March, with invitations to a San Francisco launch event expected to be sent out this week.
The new iPad models are expected to offer a much higher resolution Full HD screen.

Bloomberg reports that iPad 3 processor will be a 'quad-core' device, a step that would put Apple's tablet ahead of competing devices such as Samsung's Galaxy Tab 10.1 in terms of computing power, and enable a new generation of high-powered apps.
Tech site MacRumors claims that the new models will also be more expensive.
'The iPad 3 costs $80 more for the equivalent Wi-Fi models, and $70 more for the equivalent 3G models,' said MacRumors, reporting on leaks from Chinese factories.
