Will we see 3GB of RAM on Samsung's 2013 high-end smartphones?

Prototype handsets suggest Samsung is testing a phone with no buttons and 3GB of RAM

A leaked photo of a pair of Samsung 
phone prototypes shows them labeled as having 3GB of RAM. In addition, you might have noticed the lack of buttons on the devices. Of course, this doesn't guarantee that we will see 3GB of RAM or even a buttonless phone in the next generation of devices from the Korean manufacturer, but it is comforting to know that such things are being tested. If implemented next year, we would imagine seeing both features (if lack of something could be considered a feature) debut on the Samsung Galaxy S IV.

The current version of Sammy's flagship model offers 2GB of RAM which is something that is being used on the highest of the high-range models like the LG Optimus G. And the buttonless look is merely the result of years of smartphone evolution. We will probably look back in a few years and laugh at those smartphones sporting 'just' 3GB of RAM and marvel how we got by so well and for so long with such low spec'd models.
