I highly doubt that side stories would get animated as OVA's or movies since they are bundled with DVD's/BD's (you know, business...) so expect them to be never animated at all. OVA's and movies are usually or always original content (new story).

As for the LN's they will be animated in our usual anime seasons though expect them to be thoroughly cut depending on their budget. I just hope it doesn't turn out like TWGOK season 2 where they skipped several important arcs. XD
