I believe both Kia and Hyundai's new model year starts middle of the calendar year, so I would expect to start seeing info about 2021MY stuff coming out in the next few months. They are not like other car companies and release new models aligned with the calendar year.
I am a bit surprised, however, given your bad luck with your current Niro that you'd buy another. I am curious as to why you are thinking about it? To be clear: I am not jeering or calling you out, just want to know the thought process behind the decision. I have had 4 cars bought back under lemon law the past 2 years. One of them was a Kia, but it was an entirely different model than the Niro.
Two models I am keeping my eye on right now: Mustang Mach-E and the ID.4.
I was ready to buy a Soul EV in 2019 and would have if the 64KW version had been available. Of the three variants, I liked it better than the Kona and Niro: better space utilization and more room in the driver's seat. I thought the Niro was a bit cramped and, as a passenger in a friend's Niro hybrid, found it extremely uncomfortable on a 2-hour ride. The Kona seemed peppy and tolerable but not available then in deluxe trim, and the dealers wouldn't sell at list price.
FWIW, I drove everything then on the market (what else? BMW i3, Nissan Leaf, Clarity variants and Prius Prime) before settling on a Model 3. It's not for everybody, certainly not if you need the hatch or if heat pump issues make or break your deal... and I didn't like the interface until I got used to it, which took about two weeks. With that said, however, it blows my mind every single time I get into it, and it's fun to drive even to the post office, never mind out on the road. For the other considerations, I'm planning to get a Model Y once they've fixed the manufacturing QA problems, which have not been a problem on the Model 3, although I'll check out the Mustang and VW before signing anything. The new Lucid looks interesting, but I don't have that kind of money.
The value proposition on all of these is interesting. My "standard range plus" (240 mile range) cost less than $40K before taxes and still had some tax rebates ($1,875, not $7,500); tricked-out versions of the Kona and Leaf were about $5K more than that but with a larger rebate, so the purchase price was fairly close, but I believe the Tesla will be worth more at the end of five years. The last time I checked, you could still buy a "basic" Model 3, on the phone or in person but not online, for around $35K, with the range limited by software to 220 miles.
Of course, this is just my $0.02 based on personal experience. YMMV.
