Daring Fireball‘s John Gruber today makes note of his complaints about iPad magazines (all valid), including the large files and static page sizes. But he also mentions casually, but apparently factually, that the iPad 3 will have a 2048×1536 Retina Display:

These magazines and newspapers that render each “page” as a static 1024 × 768 image are going to look like utter ass on the iPad 3’s 2048 × 1536 retina display.

Unfortunately, there is no timeframe given to this and with some expecting a Fall upgrade and others putting the release update as far out as next March, we’ll have to wait and see.

We earlier found bits of code which seem to indicate that an upcoming iPad will indeed have double the resolution as the current iPad 2.
