It sounds like it's just the big machines (Segway PT i2 SE, x2 SE, etc.) that are being discontinued.
They only account for like 1-2% of the company's revenue these days, according to the article at the Verge.
Still, that's very sad. I love love love my i2. They're such great machines.
I wonder if it makes any sense to buy one of the last i2 SEs before the stock runs out.
