I would love any new iPad to be 16:9. I guess in the UK here 16:9 has been around even way before HD and it is not the same in the USA but I hate not having videos that are 16:9 go right up to the edge of the screen without zooming and cropping the image.
If Apple made a Touch/Pad around 7" I'd buy it, I actually like that size for tablets. Sold our iPad 2 b/c I rarely used it and gf mainly did however she couldn't bring it everywhere, so got her the Fire and it fits right in her purse. I think they'd sell a lot of the product if they had something around 7". I'd rather see that than a phone variant around 5", but everyone has different opinions
