The V series is a one-off thing Intel did, but they don't have a direct successor planned.

Previously, they had a P series of mobile parts in between the U and H series (Alder Lake and Raptor Lake). Before that, they had a different naming scheme for the U series equivalents (Ice Lake and Tiger Lake). Before that, they had a Y series for even lower power than U series.

So they mix up their branding and segmentation strategy to some extent with almost every generation, but the broad strokes of their segmentation have been reasonably consistent over the past decade.
