Saw this article over at Engadget. Samsung's new chip could put 4GB of memory in your next smartphone basically it says Samsung will be ready to start mass production sometime in 2014. It also states it uses less power than their current 3GB chip that comes in the Samsung Galaxy Note 3. Looks like I'll be getting a Note 4 or 5 after all depending on when they actually put this chip in their phones.
Anything that improves battery life and makes the phone faster sounds good. 64 bit processors will probably start showing up soon as well. EDIT: Looks like the Galaxy S5 might have a 64 bit processor: http://bgr.com/2013/12/30/galaxy-s5-specs-64-bit-4gb-ram/
