I shouldn't think we'll see changes in the next couple of years really other than in the the manner of PR/presentation (as we already have with Tim Cooks frankly lackluster performance) - Steve will have had oversight of everything coming out in the next 2 years or so but obviously not the final polish - again it's a debating point
Also there's the fact that has he left some of his 'DNA' with Apple - has he set the company up in a good position to succeed after he is gone, or is this simply not something Steves can truly do? Was Apple too personal to Steve? Is it even possible to define what made Steve Jobs the person he is and in turn what really made Apple a success?
Tim Cook must have known that Steve's death was imminent, it would've been hard to present a keynote which Steve would normally do in a situation like this.
