I think the whole Cazador design concept has been laid to rest, so to speak, and we ought to just get out and enjoy any good Tesoro we have or can acquire. I don't ask for or expect anything new from Tesoro until it is actually a finished offering and released to the general public. We know that Tesoro hasn't been and likely isn't going to be one of the major design manufacturers, and shouldn't expect it to happen. Not unless substantial funds come along to acquire the design engineer and other product development, as well as marketing to build the Tesoro brand dealer base.
The last 20-25 years has seen a very rapid-pace growth in electronic designs with lighter weight models being the norm, sporting all sorts of visual and audio features and functions, and more developed digital circuitry engineering. Let's face it, Tesoro isn't there in the design field, and they are far short in the modern TID and VDI display and Tone ID market. They have lost a lot of dealers in the recent decade or so, so I think it best that we all just sit back and make use of what works.
Not fuss about models they might think about making or names that have been bounced around, but instead look at what they have offered and currently provide us. Tesoro makes very good working detectors for certain niches of the market. I have several brands and models, but my Tesoro's lead-the-pack when it comes to providing the best performance in dense iron nail infested sites which is what I look for and hunt the most. I have for many decades now and nothing matches a Tesoro, ... fact. A few newer offerings might come close, but only close, not quite enough to match or better a good Tesoro with the right coil for the task.
If somebody wants a new detector with different features than what Tesoro currently offers, there are plenty on the market to shop from. But if you want Tesoro performance, and the strength that Tesoro has really had in their favor since mid-'83, get one for how well they respond and quickly recover in any dense iron littered site. Their light and handy feel and balance, and their durability. I have had, seen and heard of more glitches and failures with so many modern detectors, where most Tesoro models have been pretty glitch-free, and perform almost forever with out any failures or need for service.
If you're like me you can have an older Tesoro model or two or more of them, or get a newer and currently offered unit like an Outlaw or Vaquero or ???, and you will have a detector that is proven, holds up well, has a good assortment of available search coils, and will excel in most typical detecting scenarios. Use what we have, and forget about models that haven't been, or likely never will be, brought to the market.
Just my opinions, and remember they come from a Tesoro fan of 32½ years who owns and uses more Tesoro's than any other brand in his arsenal ... because they work. Simple!
