Now what would Fukasaku be reffering to if not to sage mode.
Gamabunta who knew Minato, asked Fukasaku if he also saw those familiar forms. and Fukasaku simply replied with Naruto surpassing everyone of Konoha's older generations. Which is probably a little exaggeration from Fukasaku's part.
"Those who came before him"? I remember when the spoilers for this came, there were different translation for this line. One of them said that Naruto had surpassed Jiraiya and the 4th.
Probably translation differences, don't make a big deal out of it.
