If it is, color me surprised, as Bards are probably the last class I expected, based on the overall complexity of the class and what their implementation will mean for the game's development future. The way Larian handles how Bardic Inspiration works is going to be a big indicator on how things like smites will work down the road too.
At the very least, Bard means we're getting a glimpse on a possible reworked reaction system.
