I don't think it's reasonable to blame V/T (or Aliona, whose new partner is unproven anyway) for the split. It's not their responsibility to "step aside and give others a chance." I highly doubt that's why M-T/M split. It's their partnership, their decision, and I trust they're not foolish enough to let the actions of other teams be the main guide on what they'll do. I don't think they were adamant about staying after Sochi solely 'cause, "Oh, V/T and S/S will be gone, MEDAL GRAB TIME!!"
