Well, here's the thing:
Soul Eater started out as a 日本漫画 series. The 日本动漫 is an adaptation of that manga. For the first 34 episodes 或者 so, the 日本动漫 was pretty damn faithful to the manga. Of course, the 日本动漫 studio noticed a bit beforehand that they were running out of 日本漫画 to adapt, and they only had a 51-episode budget, so they did the best possible choice: they diverged from the original manga's plot and took their own spin on the duration of the season, tying up as many of the remaining plot points as they could for a premature ending. If 你 ask me, they picked a wise point in the story to 分裂, 拆分 off from the anime. Otherwise they'd have to add 更多 plot points that would risk being unresolved in the end.
As we speak, the 日本漫画 is still being released, with no foreseeable end currently in sight. The characters and a few major events are all developed quite differently. If 你 can find any copies, I definitely recommend 你 read them.
Now, as for the 秒 season:
The 动画片 studio responsible for producing the original 日本动漫 is "Bones", the same studio that brought us Fullmetal Alchemist, which was a very loose adaptation that ends up being developed differently has requested 由 the creator of the series. Now 识骨寻踪 has made Fullmetal Alchemist: Brotherhood, a new adaptation that follows the original 日本漫画 更多 closely.
What does this have to do with Soul Eater, 你 might ask?
Well, word has it that the producers of the 日本动漫 are considering waiting for the Soul Eater 日本漫画 to play out for a bit longer. Maybe when it's close to finished, then a new season, 或者 perhaps 更多 appropriately, a whole new Soul Eater 日本动漫 will be produced.
It's just a rumor best taken with a pinch of salt, and 你 can find it in this video:
