I'm looking forward as always to new IP's. I think whoever can show the most high quality new IP, with some diversity, along with a selection of proven franchises, is deserving of the best at E3 award.
What you have listed in the OP are all existing franchises with plenty of installments already. It's exciting, sure, and there is the possibility of a franchise taking a new direction, but it's not the same as showcasing something completely new and fresh. As such, a new Mario, Zelda, Metroid etc. would simply not be enough in my opinion.
I prefer Sony franchises, but if they just come out with a new Uncharted, GOW, GT etc I'm not gonna be overly happy. I'm personally very much looking forward to Microsofts press conference, I have a feeling they might be the one this year to show the widest variety of new and exciting IP.
