Okay, so technically Voltar won't be more omniscient (is that even possible?), but he will be getting a nice buff in the Awesomenauts 1.4 update. Specifically, his healbot is getting a nice buff.

Furthermore, Coco will pick up some new upgrades, including a "blaze" effect for her lightning ball and homing electricity particles for her shock attack. The latter looks particularly nasty, dealing lots of damage up close.

Patch 1.4 will be released next week.
