I bet Hasbro backed out of the deal because they wanted to make a certain per-unit profit and the only way to make that profit would be to set the selling price at a level where they knew it wouldn’t sell.
The BS or Disney sabers are still toys, but because they have metal hilts with long, bright LED blades it’s easier for the consumer to pay $100+ for a ‘toy lightsaber’. But a plastic toy lightsaber- no matter how cool, is seen as something that should have a lower ‘toy’ cost so you can only charge so much for them.
I think the Power Saber is really cool, but I’d never pay $60 for it. Hasbro probably needed to sell them for $75-$100 to make the profit they wanted but they knew if they tried it would be a big financial loss for them.
