Actually, it's not.

If Sony can get it right (make it manufacturer at a "reasonable" price) this could be a game changer bigger than all of this mirrorless stuff (actually, many of will argue that mirrorless wasn't really a game changer - but that is another topic).

This has the potential to make it possible to put really small, simple lens designs on bodies and have IQ on par with the most expensive glass available.

The curved sensor myth gets debunked here every few months.

Read the papers that accompany Sony's work. The sensor is curved because they stressed the substrate to alter electron mobility. Now that they've proved that this is a good thing to do, they're working on ways of inducing stress while retaining a more useful flat sensor. In short, the curvature was an unpleasant side-effect of a useful research path.

Some PR guys got ahold of this and went all psycho, the way PR guys do.

Optically, the curved sensor counters one aberration, curvature of field. It does nothing about spherical aberration (the primary resolution limiting factor for fast lenses), astigmatism, chromatic aberration, or distortion. It simply makes lens design more difficult.
