Big doubt, they have obviously been right to focus on hybrids for the current market. What makes you think they will not be able to compete on whatever the next pure EV cars look like?
I just bought a car. Avoided electric. Too expensive for what it is just now.
Car would have cost twice as much and that allows me to easily buy 10 years of fuel and running costs let alone accounting for depreciation. Charging standards and user experience needs to be better still.
Hoping in 5 years or so when my other car is ready to be replaced that the decision goes the other way, but we'll see. For now it's a no go.
I expect that Toyota will have products ready when the time is right.
