I imagine so. We've never had just the lions when a Voltron show came out, or a Voltron show with no toys.
Overall, I didn't think it looked bad, but (and admittedly basing this on a short promo video means little) It doesn't appear to bring anything new to the table. It looks mainly like the same old stuff drawn by a different animation team. I do rather miss the "presentation" of forming Voltron though.
