if we assume 5.4 will be put on the ptr as fast as the other patches and assuming blizzcon occurs sometime during 5.4 how soon do you think it will be until we datamine what it is, considering all the blizzcon items have been murloc related (and even if it isnt murloc related unless its something from titan we should be able to recognize "hey blizz reference") it shouldnt be that hard to spot.
also post your speculation about what it might be. also remember that blizzcon pets that are themed have always been themed for UPCOMING games, so unless the sha are going to be in the next expansion we arent likely to get sha touched murlocs
if burning legion a murloc dressed up as a demon hunter, id suggest a kj murloc or something like that but im afraid it would end up looking to much like murkablo
if naga/south seas a murloc which instead of legs has a tail like a naga a narlock if you will.
if blizzard all stars and bas keeps its art style it had at blizzcon i expect a "titany" murloc (the characters in blizz all stars kind of look like titan constructs if you dont know what i mean look up blizzard all stars)
if titan who knows, we have no clue what its about so i have no idea
if starcraft maybe a protoss themed murloc
if diablo id assume it would look liek whatever class they add or the big bad of the expansion
if its a mount i expect it to look similar to the big blizzard bear only themed after the next wow expansion, or might even be something else FROM the next expansion but ith a unique skin and murloc on it
or they might throw us a vanity curveball and have it be something like the murloc suit or they might give us something non murloc themed although if its not murloc themed i would be very very upset, i know it seems silly but its tradition i go to blizzcon and i expect murlocs, i love murlocs.
