Are they gonna do what honda did with the Honda E and charge way too much for it?
I wouldn't have thought so. The Honda e is their only EV, and the Japanese govrenment has been trying to push hydrogen, so they didn't want it to be too popular - so the R&D had to amortised over a smaller fleet, so each car has to pay a higher amount.
The Leaf was released a long time ago, before the government realised they had lots of fossil hydrogen stores which would be stranded if all cars were pure EV. They're starting to come around now, as climate change bites, and around the world fossil bans are being planned in the next decade. Finally Toyota has released a pure EV, which feels a decade late given their experience with the Prius.
NIssan has had difficulties, and the Ariya and new Micra are built on Renault platforms, and Renault aims to start the new 5 under £20,000 - I doubt that will happen, but they'll try, and it can't be much more than the e208 or Fiat 500e.
GIven the styling, and Renault trying to move upmarket, the Micra has to be cheaper than the 5, in much the same way the Corsa is cheaper than the 208 - identical underneath, but with a less desirable brand and arguably worse - certainly less interesting - styling.
