I highly doubt we see this happen again, at least among top players. There are a lot of factors that made this situation possible at this exact moment and situation. You can argue the spectators were robbed of a good game, but since both players were ok with a draw because of the tourney format, I would argue they saw an event in chess that is interesting and unique... way more interesting than another 20 move snoozefest where both players setup defensively, trade down then draw.
