Ichigo lost his powers, meaning both Shinigami and Hollow powers. After all the Hollow side did say: "Zangetsu and I are one and the same. Whoever's power is higher, they will appear as the dominant form. "
I mean, maybe they intend to continue bleach? The ending was too dreadful and sad. After all, Ichigo's dad does know a lot about the Final Getsuga Tenshou technique and it was strange how he no longer had his powers until we witnessed his fight against that arrancar. Or maybe his father never performed the technique? But that could have to do with Urahara's involvement. He could still have a method to regain ichigo's powers. Also, it doesn't seem that Aizen is really defeated yet. I mean, he still is very much alive and possibly still dangerous. I don't doubt that he already forsaw this outcome.
