To me it's the same as it was 4-6 years ago, the only differences now is with the increase frequency of events it just highlighted more. Look at the stats of events:
2012-31 events this year
Realistically they could spread out fights more and we would not notice the hits. For example after UFC 148 they were 4 events prior to tmr's fight. Then you have another 2 events and a PPV in less than a month's spam from Jones vs Vitor. To me the main problem leading into the future is they don't have enough star power to make every PPV marketable.
