Nokia EOS : Expectations ?

Given that the Nokia EOS is more or less confirmed now, what changes do you guys expect apart from the obvious 41 mp camera ?

1)Do you expect OIS to be built in ?

2) Higher res screen ?

3) Snapdragon 600/800 ?

4) Windows phone 8.1 ?

Could microsoft possibly reveal WP 8.1 at Build, ready for EOS ?
