Perhaps unsurprisingly at this point, we're here to report another delay, this time concerning the first shipping wave of Playdate handheld gaming systems.

Previously scheduled to be sent out later this year, the first batch of 5K units suffered battery issues. The units had to be sent back, their batteries replaced with brand new ones from a different supplier. Needless to say, this meant a delay into early 2022.
