Most likley alot since Hummingbird will take full effect in 2014. Plus there will always be SEO updates from Google. But then again like chrisgaza said " prophets of doom have been there in seo since 101. as long as people are looking for things online, seo will always be alive and kicking"
You'll likely see localize search improving. Social media will play a more important role in acrediting local business listings. Google+ will be vital in the scheme of evolving these things but Facebook triggers will be basically non-existent in Google results.
If I was to predict anything at all search related it would be that Google will experience a bit of trouble internationally as a result of ongoing Snowden revelations. But they won't be alone. Microsoft, Facebook and Apple will suffer a bit from that internationally too.

I don't think that PPC can take place of SEO in 2014 bcz PPC based on paid marketing which is to costly, whereas SEO is a organic marketing.. May be in upcoming months Google will do some updates and algorithm but I don't think through those updates a white hat SEO will be effected
Yes I agree with mildred2013 comment that is : seo is here to stay, social media is just another cog in your overal seo strategy. Now a days normally SEO guys are also performing SMO activites which is a plus point and really beneficial for a site. Through SEO we can get traffic from search engine which will take some time and with the help of SMO we can get direct traffic on our site which is beneficial to get organic rank
Social media will surely play an important role in promoting any website but things would not be much different from 2013, you should be using unique content all the time and use as many different ways to get backlinks as possible and make sure that you do not build spam links. Quality Backlinks with quality content would still be the key to get good search engine rankings.
