The next generation are slowly making their mark. I wonder whether next year will see at least one of them win a GS. The Big Three have been so dominant that the generation in between (which includes Nishikori) haven't really been able to make their mark and they're getting too old.

It's worth noting that out of the upcoming big four, three of them have Russian connections and are fluent in Russian.
