i have recently bought a 7d and only have the 18-135 that came with the body. i know this question has been done to death but i have only always found a 100 - 400mm compared to either 70-200+1.4/2x or 300 4L+1.4. but im an avid (albeit amateur) wildlife photographer. what would be a better addition to my lens collection in the long run (i intend to upgrade to a full frame at some point much later) especially considering most of the wildlife/safari photography is done in low light conditions (at dawn/ dusk)
70-200 + 300 f/4 + 1.4x/ 2x 
100-400mm +1.4x/2x
i understand the budgets for these two would be a little different but that's not a constraint unless it makes more sense to buy the 100 - 400 for now and save the rest for a 400 2.8 or 500 4 prime. 
please advise.

400 f5.6L for birds and "distant" wildlife.

300 f4L IS for close birds and wildlife, and for low light.

This combo outperforms the 100-400 in virtually every aspect (except maybe sheer Fun).

Except, as with many of my best shots, a bird comes zooming by at closer than 300 mm, in which case you're SCREWED.

I really like my 100-400. I also have the 70-200 f/2.8 II, and the 70-300L.
