1, 3 and 4 should be no problem. We already have phones that achieve those.
For 1, I'd throw 3.7 into the mix, and possibly 4.5 depending on thinness and profile. For 2, I'll agree and insist that my next phone has a high res display. Not cause I think the screen on my current phone is awful or anything, but I saw the Note and some other phones at AT&T and I could definitely go for high dpi displays.
In terms of 5, 16 gb's is not enough, trust me. I have a 16gb phone right now, and with a decent amount of music synced in, some videos I shot with the camera, pics, apps, and podcasts I only have about 3gb's left, and I still have a whole year left on my phone contract. I'm definitely not buying a phone unless it either has 32gb built in or with an option for expandable storage.
Honestly, I see Windows Phone 8 giving us all the kind of hardware we all crave right now. The real question is how they push forward on the software side. Not just with 3rd party apps (I'm actually fine with the current progress), but with the OS itself:
How do they improve on the voice dictation features? How do they evolve Bing? We know Mango gave it a bunch of new features, how do they expand it even more? Is IE10 going to be competitive with the Fall version of Safari and the Android browser? How do they evolve the People, Picture, and Music hubs? Can we get new Hubs? How do they effectively deal with notifications? How do they push the live tile concept forward? Can they be bothered to update the core apps (mail, people, music, picture, bing, etc.) independently of firmware so that we don't get as badly shitted on by the carriers? Skype, are they done dicking around with that? Can we get a badass app out of that or what?
I can do this all day folks.
