That brings up the question of whether he will be promoted to juryo or not. Anyone has thoughts on this? It seems he'd need help and luck to get to juryo in the next basho.
I'd say that it will be difficult even with a 7-0 result to skip a 5-2 result that is six rungs above on the banzuke ladder, but the yusho might count for a few rungs more. Even then, there are four rikishi in the top of the Makushita joi with kachikoshis that have a greater chance of returning to Juryo.
It all depends then on the big shuffle in Juryo. There are going to be quite a few demotions in Makuuchi and Juryo rikishi moving up freeing their spots. At the same time, there are Juryo rikishi with bad makekoshis but only two certain of demotion and the fight for kachikoshis isn't finished yet. So we'd have perhaps six Juryo spots freeing up that could give Terunofuki a chance. Or some of the Makuuchi demotees get a little banzuke luck and Terunifuji will be at Ms1 next basho. It could go either way... it all depends on whether Hoshoryu and Irodori get a makekoshi which will give Terunofuji greater chances.
