Because it is kinda boring? Just like M2 is much less interesting than M1. Current gen Intel or AMD chips are like 10% to 20% faster than apple (which apple acknowledges in their marketing and hence points at performance per Watt). Intel uses about the same energy at idle but about double at load. AMD has about the same efficiency (work per Watthour) under load but worse idle. And now nothing is happening until the next release.

Yeah, nobody cares unless something new comes out.
