We wait all these years for a homologation special (Toyota Yaris GR-4), only for the WRC to switch to spaceframe chassis...

For me, unless moving to spaceframe chassis definitely brings in more manufacturers, like Suburu coming in with a scaled down Impre(tend)za(?), I'll personally really lament losing the only real tie to production road cars. Part of the appeal for me is manufacturers having to transform what they're sending down production line into what we see out on the stages.
