Rötschreck, Psyche!, Death Seeker

Can Death Seeker cancel the Psyche! played to circumvent a Rötschreck?

Rötschreck
Master: out-of-turn. Frenzy.
Put this card on a vampire when an opposing minion attempts to inflict aggravated damage on him or her, whether the damage would be successfully inflicted or not. Combat ends. This vampire is tapped and sent to torpor. This vampire does not untap as normal. During this vampire's next untap phase, burn this card.

Psyche!
Only usable at the end of combat when both combatants are still ready. Begin another combat with the opposing minion.

Death Seeker
Cancel a combat card played by the opposing minion as it is played (no cost is paid). A vampire can play only one Death Seeker each round.

Compare and contrast to Watenda.

Yes, since Psyche! is now played during combat.
This reverts the Watenda ruling.

Correct.
Watenda, Death Seeker, Botched Move can be used to cancel a Psyche! (or a Taste of Vitae) at the end of combat, should that end be caused by Rötschreck or by the lack of presses to continue.

Psyche is now a combat card played inside combat, therefore Death Seeker may cancel it inside combat and Rotschreck would play as normal.
