It looks like they're just calling it "iPad" now on their website. It's an interesting idea; maybe they plan on always calling the current one "iPad", and renaming the old model something like "iPad 2012" once the 2013 "iPad" is released.
Although admittedly we already have that with most of their other devices ("do i have an early 2011 MB or was it the mid-2010?") and it's not like other vendors are much better in this regard.
