is anyone planning on buying the ES100 30mm?

Me too...my main reason would be that the increase of actual and apparent FOV compared to an already large FOV 31 Nagler is not very much, and to get that extra would cost a difference of $750 compared to the fairly easily available used/nearly like new price of a 31NT5 (which I bought new in the incredible Hayneedle + TeleVue sale a few years ago -I bought it new for nearly the same price as a used one).
No, not me, for all the reasons you mention.

It comes with a 3.5" focuser and should be able to make use of the full field stop. And the cost of this EP is less disproportionate to the cost of the scope. Once you've bought the 160 mm Apo and suitable mount you've dropped $20 grand or so. What's another $1200?

Kudos to Explore for taking risks and pushing things a bit.

I believe the large secondary makes this EP impossible for the scopes that would be the best customers for this. Because it would be great to have the extra fov in a large dob but, balance issues would be hard to deal with as well. The 25mm is probably the best we can hope for.

This eyepiece will be perfect for any scope that meets four requirements: flat field, coma correction and good illumination at 52mm circle (eyepiece field stop), and f/5 or slower.
So, C11HD and C14HD meet all perfectly.
Any refractor with 3.5" focuser and focal length starting at 1200mm will meet all requirements perfectly.
Dobs will not comply until a larger coma corrector is available. In any case given the trend of dobs to go faster these days (f/3 to f/4), a 30mm focal length is not important. Large f/5 dobs may like it when large coma corrector is available.
I plan to go with a 24" f/3 in the future, but I will use a Ethos 17 there. Meanwhile, the 30/100 will be master of the 7" apo and C14HD.
That is it, as simple as that. I don't understand why people keep repeating this eyepiece has a very small target audience. I think they do not understand how many C11HD, C14HD, and >=6" refractors are out there, increasing every day. Of course a $1500 eyepiece does not need to sell as much as a $300 eyepiece.

Once the EP is here I would bet it finds buyers and they will prompt other manufacturers to make scopes that will work with it. Just the same as years ago no one made F5 newts with 2" focusers.
For E is peobably more of a Formula 1 product, it gives them credibility to say "we are advanced, we are cool, we have the biggest and best etc etc' its pebably worth the development cash just to be able to put it on the shelf even if they never sold a single one.

A Ha! I knew all that astrophotography stuff couldn't keep you away from eyepieces forever Helder.
If I had a scope that could make use if this eyepiece, I would get it. I already want the 9MM 120* one.
I would be interested in one as well. I'm hoping the have the prototype at NEAF in April.
