They did this with their Blu-Ray players about five years ago:

Each device had to be shipped to a repair center because they needed to directly re-flash the flash storage. The issue with the Blu-Ray players was that an update caused it to get in to a state where it would boot loop before it even got to a point that anything could be done, manually or otherwise.
What we don't know yet with this issue is whether the devices are booting enough to apply another firmware update. It may be possible to do this, fixing this issue. If that's the case "bricked" would be technically incorrect, but for now, it's not a wholly inaccurate term.
