I actually agree with this although I don't know that it will happen in 2015. Crypto can't go anywhere with a revolving door of trading leaders every few years because it's not economically viable. That said - I feel Bitcoin's economic model is broken with the trending towards 0 block reward.
I actually find Ethereum's ongoing distribution model much more geared towards what makes sense to me in a growing economic structure.
Monero and Ethereum will have a similar reward structure in several years.
So coins can just restructure? Why wouldn't btc just restructure? But really, I'm all for more coin options in the crypto world so I hope XMR or others can be more competitive.
