S1992 - S2044 just had a merge like 10 days ago, this means that your server will get the next merge. It will happen around June would be my guess. Just because they don`t make merges that often and also if you follow the history of previous merges they normally do a merge around that time before the summer starts.

I`m at S1988 which started back in August, we got our merge in December around the 5 months mark for our server. Almost every server have to wait for that amount of time i think to get there first merge (depending on how old or young your server is in your merge group). So your server beeing only 3 months old you have to wait for 2-3 more months. And you are also going to be the oldest server in your future merged group which in turn means you have to wait the longest of all of them.
