Kia wouldn't forget to include one of their EVs in their 2026 Wish Book, so your fears appear to be valid.
The Kia website currently shows 3 EVs. The EV9 is listed as a "2026" model, but the other two are listed as "2025" models. Only one of those two appears in the 2026 Wish Book you picked up.
The end of the Niro EV was predicted by the planned switch from the Niro EV to the EV4. "Changing market conditions," however, will leave only two EVs in US Kia showrooms next year. I wonder if there were stacks of 2026 Wish Books including the EV4 that had to be recycled?
