Granted it may result in Toyota losing the battle in the long run. On the other hand any large improve in batteries may gradually bring Toyota into EV world just by letting to upsize the plugins' batteries.
Personally i like very much my 2015 Prius Plugin, and the only thing i'd want about it is to have additional 20KWh of batteries (may be one day i'll throw them in myself :)
But I would much rather be doing all of my driving in EV mode. I just think it's going to take another generation of battery improvements before we start seeing affordable 3-row MPVs (which is what I drive) with decent range. The VW Buzz and Kia PV5 have well under 300 miles range, for example.
China does have some pretty awesome looking EV MPVs like the Zeekr 009, which supposedly gets up to 500 miles range. But that won't be available here any time soon.
Improvements in charging speed and improved charging infrastruture will also help a lot.
