You need to know where to look. Machines from laScala, Vibiemme, Cimbali, Wega, VFA, Expobar and many others may have E-61's under the hood, but all that's visible on the barista side is the bottom of the group and the electronic touchpads. Their mechanical complexity can mean that they're a b**** to maintain if they are surrounded by a shroud stuffed full of electronics, so they've tended to fall out of favour.

... Heck, when I think about it, even the highest end Speedster, Slayer, etc machines don't even use an E61 brew group. Do they use any principles from the E61 brew group though? (ie. Thermosyphon) ...

There are dozens of machines still employing the classic E61, and hundreds more which use (for lack of a better term) a "modified" or "proprietary" version of the E61, so I'm not sure what you're talking about.
But at the same time, you have to keep in mind that Faema developed the E61 in . . . 1961! It's a design that is over 50 years old, and we still talk about it, praise it, and use it every day! So while it's a tried-and-true design, still in widespread use today, there has also been half a century's worth of tinkering, re-designing, improving upon the original.
E61 machines still in use today? At least three restaurants and one café/roaster nearby still use Faema E61 machines, and there are a number of sources to still buy new ones. Vibiemme HX machines have "true" E61 group heads. So do Ala di Vittoria "la Valentina" machines, and similar models sold under different names.
Well, I'm not Jason but I too am an idiot if that helps lol. At any rate, he was referring to a "true" e61 as one designed as the original design. There are some that have a basic similarity but aren't in fact the same faema e61 design.
For instance, my Astra has an e61 group, but is different in that it is switch activated versus lever actuated and it also doesn't have a spring loaded chamber used as a mechanical preinfusion.

In the 70's or early 80's when faema was going belly up, Vibiemme bought the right to use the original grouphead patent (Faema has as well) Vibiemme modify it/ customized it so that's the basic story most of "other" e-61 groups are very similar but not the exact one see pictures here bottom of the page http://www.espressocare.com/VibiemmeDetails.html
