V6's keep getting bigger and bigger, and Honda and Toyota are usually anti-turbo except in their most sporty models (and Honda has only sold one factory turbo in the US—the original RDX), would a V8 engine be available in either any time soon?

And of course, each platform's many derivatives (Highlandser, Harrier/RX, Sienna, Ody, Pilot, MDX, and more)

They will soon pass the 4.0L mark, and nothing against 4L+ V6's, of course, but maybe it might be time for a V8 in them.
