His last basho? Hell no. If Hakuho chooses to continue as an average yokozuna he can compete at least 2 more years with comport. Who are the younger and stronger wrestlers coming at hem except Terunofuji? His rest and main contenders are Harumafuji and Kotoshogiku who are actually 1 year older than him and Kisenosato, Goeido only a year younger. Kakuryuu with a same age they can all stay and retire around same time.
