I think there's a good chance of Jellal making a comeback. Last chapter he thought "We are out of options here". To me that sounds more like "I have no other choice than to use that." with that being some secret trumpcard with some kind of dire conequence rather than "That's all we could do... we are done for".

Of course that might just have been a fluke of the translation, but if it's not, there's quite a bit of hope for him getting up again.
