What they might disagree about is the name, although there have been some increasingly strong hints that iPad 3 is not the name. I had my money on iPad 2s, but it seems I've done my dough!
Take the sub-slogan for the event, "We have something you really have to see. And touch." Many have suggested that the first part of that statement is referring to the use of a "retina display" on the new device.
It seems that might be true. Today, both VentureBeat and CNET are reporting the new name - it is to be called the iPad HD. Both outlets also point to an earlier story from Gizmodo which relied on brand-new parts listings from Griffin and Belkin to identify the new name; in addition there are referrer listings that have shown a device called iPad HD with a screen size of 2048 x 1546 appearing in recent months.
Note also there are also increasing stories of Apple buying up huge quantities of 7.1" screen components in readiness for a smaller iPad (the "SD" ?) later in the year.
