I haven't talked puro for a while, but man if this G1 hasn't been just amazing to watch and really got me in the mood to discuss good ol' wrestling from Japan, so I had to get an account!
The respect between Nagata and Fale at the end of that match, the tears of the commentator, the audience... what an amazing moment. Obviously I'm a big Nagata fan, and I'm sad that to have seen his final G1 match, but life goes on. I'm just glad that back in 2007 (wow, ten years already!) he got another run with the belt. I saw it as an unexpected and unlikely win back then, and to think he's still kicking (quite literally) to this day... major respect. Nagata's first IWGP reign is still one of my favourite in the history of the belt.
And I've got to echo what Oyaji said, hell of a match between Naito and Tanahashi. Naito is the best wrestler in the world, basically capable of a compelling match with anyone, and the crowd buys into him so much. It'd be a mistake for him to not win this tournament.
