It'd be pretty interesting if this is true. It launching a year~ earlier than the Scorpio, and likely at a lower price, would be reasonable justification for it being around 30%~ weaker. It would also make it likely that Sony and MS will in effect start taking turns in releasing hardware, so they'd be constantly looking to one upping each other (which would arguably encourage more competition).

they may not even take turns since PS4 and Neo would have release before the other

By taking turns i mean Neo -> Scorpio -> Sony again -> MS again, etc. One would have to release two pieces of hardware in quick succession to swap the rotation (this all, of course, assuming they both continue to produce hardware which i personally think they will in some form for a while).
