Looking at the BOM (6 cheapest servos, one usb camera, a usb hub, a microctronller ,two mics, 30cm-high low-precision plastic) the price looks fairly realistic to me. I could imagine it at half the price on aliexpress. The manufacturing or sourcing doesn't seem complicated. So overall it looks like a very realistic endeavor.

The only negative point I see: Pollen Robotics doesn't seem used to do mass market/cheap products. But as I said, it seems to be a pretty simple production (I mean, they are probably running everywhere like crazy because nothing is ready and everything is broken, but they should be able to accomplish this)
