I just got e-mail this morning, apparently the consolidation will take place "in approximately one month".
Yup. I got it too. Came here to see if anyone had anything firmer to go on. Guess not.
Also, I'd wait for the forced merge just to make sure you keep all your characters and get the higher legacy on the destination server.
As I understand it; character limits are relaxed in these instances (until you delete a character and lose that slot) and the higher legacy will supersede the lower one.
