These are all just early tech demos, so I agree with the OP on the fact we haven't seen enough.
Nintendo don't focus on graphics and have little experience designing in HD so I really doubt they have shown us what the system can do yet.
3rd Parties seem very impressed with it's graphical power with EA praising it live on stage.
I believe the (rumored) extra Ram and Vram will make a huge difference in Texture quality also 3rd parties are going to find it much easier to program for due to the less restricted memory allocation.
I have high hopes - lets just wait and see what the next year will show us leading up to the lunch
