People tend to overestimate what can happen in a year, but underestimate what can happen in a decade....
That said -
* Current economic recoveries are too top-heavy and debt-focused; businesses and investors are taking for themselves without giving back enough to the workers to provide customers and make recovery sustainable. Real terms wages aren't recovering, household debt is rising. I don't see a track record of that sort of thing correcting naturally, so I'd suggest it'll be a brake on recovery through 2014 and possibly push one or more major economies back into recession.
* Apple's iOS market - the cash cow supporting the whole business - continues to decline. iOS lost market share leadership on phones (aside - one of these days we'll start calling them tablets too, accident of history that they're called phones now) some years ago, and by some measures has recently lost it on tablets too. I see no practical way back for a single company releasing 2-3 devices a year against an ecosystem releasing hundreds. Stocks will continue to decline, I doubt they'll be more than a niche player in 5 years time. (Links - https://news.ycombinator.com/item?id=4431730, https://news.ycombinator.com/item?id=3076576)
* Mark Zuckerberg has a track record for spotting the Next Big Thing, if possibly also for overpaying for it. Facebook.com will continue its move towards being a social hub for varied sources rather than just a single entity, while stories continue dismissing its relevance. Facebook, Inc. will continue growing through this expanding footprint, whatever the core property's traffic does.
* I hope I'm wrong, but China seems to have been spoiling for a fight in various ways for some time. From its currency manipulation used to build up a balance of payment surplus which is then used to buy up real assets overseas, to its territorial stances - Taiwan, South China Sea, Senkaku / Diaoyu.... I suspect much of this is pre-emptive distraction from the fact that it needs to keep the economy growing at 7% annually to sustain their young population (and suggestions that they've been cooking the books to cover failures in this), but.... Too big a power, too much sabre rattling, too much nationalism being invoked. North Korea is clearly far from stable, Japan has a leader who wishes to paper over much of the 1931-1945 period. My hope is for China to collapse in on itself as with the former USSR; I'm not confident that we won't see war in that region in the next few years.
* Speaking of authoritarian regimes trying to use mineral wealth to paper over internal cracks and rattle sabres, Russia seems a matter of concern. Sochi 2014 is a pure vanity project; hosting a Winter Sports festival in a summer resort that's very near a region with a recent history of violent political instability (witness the recent bombings in Volgograd), building facilities in somewhat geologically unstable areas that then collapse and require rebuilding, large-scale corruption... I would be very surprised if the Sochi games go without interruption and I sincerely hope that they can prove the start of Russia freeing itself from Putin.
