I am nearly dead certain the iPad 2 is going to have the same display resolution and size as the current iPad. I am not so sure at all, though, that there wonâ€™t be a double-resolution 2048â€‰Ã—â€‰1536 iPad in 2011.
My postulation in iPad & Retina Display back on January 23rd:
I expect to see an iPad with a Retina Display announcement in 2011.
Whether that iPad will be called iPad 3 I have no idea, but I’m betting that we’ll get to see it announced before 2011 is over.
