Xena and Gabrielle will be lovers in the reboot

During a Q&A session on Tumblr, Grillo-Marxuach confirmed that the two women would be lovers, no bones about it:

i am a very different person with a very different world view than my employer on the 100 - and my work on the 100 was to use my skills to bring that vision to life. xena will be a very different show made for very different reasons. there is no reason to bring back xena if it is not there for the purpose of fully exploring a relationship that could only be shown subtextually in first-run syndication in the 1990s. it will also express my view of the world - which is only further informed by what is happening right now - and is not too difficult to know what that is if you do some digging.
