Probably, but it could take quite a while.
Makers seem to be targeting 400 miles as their upper range and about 100kWh. Beyond that, they are reducing pack size for weight, performance and cost reasons.
There just aren't many people who need a longer range than that - in Europe - it is a bit of a niche.
We have seen long range versions of many cars struggle to sell, including the MG4.
Even the long diesel range of ICE cars was never a design goal - it was simply the product of using the same size tanks as their petrol cousins, which in the case of diesel led to a massive range. But almost nobody made the tanks bigger to get more range.
Perhaps with new solid state tech, or similar, we will end up with 600 miles becoming common, but my bet is that is at least 10 years away.
