Nah. He basically just becomes a potato.
SAO is returning October, so if you wanna know what happens, read the LNs 15-18. 15 for what happened after this cliffhanger, and the rest is just for the rest of the SAO Alicization story arc. 19-20 is the next arc, Moon Cradle, while 21 is the start/end of Unital Ring. I say start/end because I haven't actually read that one yet, so I don't know what happens.
