The whole thing why SH has been released is still confusing, but the original game, dragon's prophet, has not had any major updates since 2014/2015. The Devs are taking any bits of money both games still get them but once that amount will be near 0, both games will be closed IMO. It's not a matter of if it's possible or not, it's a matter of if the DEVs still care enough to fix shit (which they don't)
Edit: the "new map" and lvl cap increase is for Savage Hunt which is a clone of dragon's prophet. Both games are from the same DEVs for some reason. Savage Hunt started back at lvl cap 40 and is getting every maps DP has. Most likely, neither will get a *brand new* map.
Those who play Savage Hunt know this already.
