I hope so. With the way this OVA ended I see a possibility that Reiji and Aila might be able to come back which of course would also mean that Sei needs to come back and give us a competition with him.
There is possibly another ova, but not the Try version.
On the RG Build Strike Full Package there is Leaflet showing there will be extra battle coming soon, but the logo title in it is the logo for the original build fighters, not try.
