Where do Apple go next?
Apple will cope fine without SJ. Although he was was very heavily involved in the product development lifecycle, he didn't personally invent everything Apple did, you know. What he did do is surround himself with good people, motivate them, and know how to pick a winner. Those people are still there. Most importantly he taught them the value of design and not to accept compromises.
Apple is defined not so much by what it releases as what it doesn't release, namely crap. Sure they have some flops, like MobileMac, but for every product that's released there are dozens of internal prototypes that are developed, almost to completion, but then dropped because they're not good enough. What makes Apple different is having the courage of its convictions to maintain those standards, even in the face of all the pundits telling it what it has to do. (Remember everyone who said Apple just had to bring out a PDA? They ignored them and waited until they were ready, then came out with the iPhone and changed the world.)
Steve Jobs is gone, but the company he built that epitomises those values still exists, so there's nothing to suggest they won't carry on producing great products just as they have in the past.
