Seems very optimistic. But surely LTC has not offering nothing new, now just another altcoin. And XMR clearly has new stuff in the cryptos market. For me is a problem that the first CryptoNight coin had such an horrible launch (Bytecoin).
Litecoin & Monero are similar in that they both took a shitcoin idea (LTC- Tenebrix\XMR- Bytecoin), optimized the code and marketed a little better with a fair mining launch. LTC was "innovative" and new and has been a success for the past couple years and I think rpietila is on the right track with thinking that XMR can potentially fill that gap in the years to come
