Well JPN is not getting 3 wins here, meanwhile CHN is one win away to secure 3 wins. XD is definitely Chinese to lose. SYQ's unexpected upset. WD is without a doubt JPN's.
i would not consider it an upset if endo/watanabe win. watanabe is fast and they are both smart shot makers.
Endo/Watanabe have 2-0 h2h against Li/Liu. Their loss would actually be the upset especially with Li's sort of knee injury.
Endo injury can be more serious but yeah both pairs are injured and this can end in retirement for any of these pairs. crazy
