Looking at some enb's they really have changed fallout do you guys imagine in a couple of years how they'll make new vegas look even realistic. Also what do you guys think enb's will go in the future?

includes SMAA injector,  which looks much better imo

everything you need in an ENB

No matter how good a game looks, it can always looks better with sweetfx and ENB . Though I suspect there will be any 'realistic' enb coming out for Fallout NV, because by the time ENB was that advance, they will probably already give up on that game and move on to Fallout 4 or some other Fallout if there is any .

Honestly the enhanced shaders ENB is pretty good if you are looking for a realistic look to the game. All it really does make it look little bit better and has more of a real life feel to it. It's Kinda crazy to me how hard it used to be and how easy it is now to mess around with the ENBs to create your own feel to the game. Plus the other ENBs that change the game entirely to fit your play style is pretty crazy. But that's really my opinion ENBs will only continue to improve.
Much Love
