Goto sporting a new costume, announcing the imminent debut of a new finisher and topping his group = I think plans may have gone tits up. Though it seems a lot more likely now I never bought the inevitability of Shibata walking in and topping a group with the cream of NJ's biggest stars, and Goto beating him tomorrow to win their never-ending feud would've completed the trilogy of New Japan G1 push tropes along with 'group of death won by unfancied homegrown' and 'group winner pins champion'. Goto's win over Okada makes a lot more sense for a future title clash than Makabe/Tanahashi/Kojima's would, though seeing as Okada's 100% in singles tournaments so far and generally hyper dominant maybe they'll go down the champion-as-finalist route which hasn't been done since 2007... when Nakamura mucked plans up by separating his shoulder.
Depending on what precisely you meant by outside the G1, I'd recommend the 2011 tournament final between Naito and Nakamura. Not his best match, but I consider it a coming of age moment not only for Naito but also for the 'new' Nakamura you commented on earlier.
