That's the thing, I don't think Zeke will die without being eaten because his Beast Titan is extremely relevant to the plot. Once he's dead Eren will be unable to use the Founding Titan unless Historia becomes a titan, most likely she will take the Beast Titan from Zeke.

Though I suppose she could inherit one of the Marleyan Titans as well since most of them are within reach on the island.
