I have a feeling that Kintoki's parts will be used to rebuild Tama, now whether or not Tama has the same mind, personality, and memories...time will tell
My theory was a bit more cruel. I thought Kintoki would be repaired but not Tama, because she's technically not a work of Gengai (maybe there was a part he can't fix without Ryuzen), then Kintoki would have to live the rest of his robot life bearing the guilt of his comrade's death.
