Well.
vB version will follow wBB version in terms of version number and features.
Currently the wBB version is in 2.3, and for the 3.0 version Summons are planned.
So then this will get it as well.

o and btw theres a Monster Arena out for wBB, that is still in 1.0 version and its been said to contain bugs.
When the 1.1 is out, Ill also convert that and include it.
During the time when this didnt work I dabbled in writing addons of my own, and learned a few tricks, so I can also make addons on request once its released.
Unless I think its a really cool idea and want it I dont know if I got the time to do anything huge, but if I think I can fulfill the request I will.
