However, I'm not sure if a 7.9" display even with retina would be comfortable enough for reading comics in double-page landscape mode. 16:10 could still have been okay for landscape but the issue with new Android tablets with ICS/JB is you don't get access to the full 16:10 resolution because of the status and navigation bars. That said, Apple's closed system is quite stifling so I've actually been looking into Android tablets with 4:3 2048*1536 displays. Right now, that's mostly China tabs but Archos is releasing a dual-core 9.7" Titanium HD and has announced a quad-core 9.7" Platinum HD. I don't think performance of either is quite up to snuff just yet but I give it a year or so and I expect we'll see inexpensive chipsets capable of driving FullHD or retina display resolution.
I find the iPad Mini very interesting primarily due to its weight. If Apple manages to maintain weight and battery life with a retina display version, it's a maybe leaning strongly towards yes.
I have a 10.1" 1920x1200 tablet and it works much better for my eyes than a 7" model regardless of resolution. A 7" ends up providing 47% of a North American comics page and my almost 50-year-old eyes have trouble with the half-size lettering regardless of how sharp it is.
