Looks like TotalBiscuit on Youtube (one of the largest game streamers) has a bricked PS4 as well.
Although his involves the optical drive no longer allowing disks to be inserted.

I don't think that qualifies as a brick then.
A brick would be your Xbox360 RRoD-ing, and not being able to do anything from that point.
A PS4 without a functional optical drive could potentially still play every single game in existence, and use every feature, aside from BD-viewing, obviously
