Google caffeine does not mean that it entirely replaces old Google. It means that Google is modified in its way of indexing, retrieving and displaying data. It will be able to present real time data from facebook and twitter. You need to have quality content since Google does all this to serve users the appropriate results.

Google Caffeine has been developed to find the highest quality content in the fastest possible time and then to present it to the end user in real time. Producing and posting high quality content to your website and then actively promoting it online will be critical to building authority and achieving SEO rankings.
