Ok, yes, I realize how silly I was for checking the Polyend store when everyone was saying that Polyend had dropped the price. I realize I’m getting old and every time is more difficult for me to understand capitalism. 
Thank you for the information!
Quoting the Polyend Newsletter distributed today:
Tracker Flash Sale
We have partnered with Reverb.com for a limited Tracker flash sale. The sale is happening now until September 4th or while supplies last!
The sale price is $359 / €399
Prices may vary based on VAT and other taxes. After the sale the price of the tracker will return to $699, so don’t miss out. Trackers will continue to be manufactured so this isn’t your last chance to get one, but it may never be at a price this low again!
Also for the record, Polyend released 1.7 today and said that it’s not going to be the last update.
Mitch had already answered yesterday, and today we got a clear reverb of that message. 
The conversation is continuing on Tracker 1.7 firmware update is available.
