the look doesn't matter, the ipad has a functional design and there is not much you can do with it and there is not much that it needs to be done either.
What is important is the specs, is there 1+GB RAM this time around
is it a faster dual core or quad core (keep in mind that 2 fast cores are slower when it comes to application performance than a 4 slower cores that overall add up to faster performance (but that only happens with a application is fully threaded (which is rare)
If they can make the CPU faster, and also add more RAM 1GB is ok but 2GB will be great.
It also needs a better camera, given the size of the tablet, a larger lens and sensor can be added (larger than what the video shows)
And most of all, the biggest improvement will not be from the screen as the content will be scaled, the largest improvement will be faster flash memory (if they decide to add it)
having around 20MB/s for a tablet is not good enough, if they can get it to around 100MB/s then you will see things like ipads booting in 5 seconds or less especially if there is a faster CPU
