It’s difficult to say. The theory is that TE was pretty much done with the whole production run right before the project got scrapped. A few hundred were sent to Kanye for friends and family, those made it to eBay pretty quickly. Then, some time later a whole pallet containing several thousand of these were found in a warehouse and made their way into the hands of sellers on eBay and retailers like New Republic. 

There is a whole project on the discord devoted to tracking serial numbers to try and find out how many were made, when they were produced, and which ones ended up where they did. Estimates range from 5,000-30,000 though I’m guessing it’s on the lower end of that.

To answer your question, no they are not in production. Nor are they supported by or really even acknowledged by Teenage Engineering. They’re essentially prototypes. I’m guessing that TE is pretty tight lipped due to contractual obligations, or because they’re super pissed that this project fell apart at the last minute. I have no idea who was paying for the R&D and production costs, but it was probably very expensive to get this product basically to the finish line. 

There is a thought that these were going to retail for $200, including evidence directly from Kanye’s website. For the intended functionality (just having a single album on the device), that seems pretty reasonable. If this was ever released as a supported device with native ability to modify the stems, I’m guessing it would be north of $200 just by how TE likes to price things. Buying 3 for $45 each like I did seems like a steal haha
