Sheeva will NOT be a boss. If the bosses are not playable, then all characters from MK trilogy will make the cut for the 26 character roster of this game, excluding classic sub zero and one of the smokes. But then again, Quan Chi is in this game, so thats one character from MK Trilogy that is eliminated from the initial roster... and we have the possiblity of a human sektor, so thats two MK trilogy characters out the window, unless Quan Chi and Human Sektor are DLC. The eliminated characters are probably not stryker, nor kabal because we heard their voices... So sheeva might not be in this game potentially, after all of that considered.
