I wouldn't be SO harsh with eDT's compared with eJets.
They obviously lose mobility and some durability (no agile), however don't underestimate the ability to hand out power tokens (especially if you consider, that 2 dts can acutally hand them over to each other). I ran some calculations and it appeared, that eDT with token deals the same amount of damage on range 6, that eJet during his range 2 attack. As a result they provide empire with some mid-range damage potential (which I hoped eSentries would). Also note, that longer range means more survivability, because you won't be forced to rush them forward in order for them to be effective like jets, which enables hit and run attacks. Feeding Vader (or even eJets) with block/evade tokens also feels very strong.
Opportunity to single or double activation is also very handy not only because of round 1 stalling potential but, taking into consideration their quite good range, sometimes you just want to make one attack and fall back, while there is no viable target for the second unit. Also note, that they can really benefit from concentrated fire (which is quite hard to use with jets because of their limited range).
as for strength in numbers potential it lets you activate two dts in a row (thanks to their ability) and then stregth in numbers into eJets (cost of 1dt and 1 ejets group is 11), which gives you 4 strong figures activation whith a 1 point card, that normally doesn't find any use in imperial lists (and then possibly squad swarm into another eJets for a whooping 6 figures (and 24 points) activation).
Also IMO they synergise very well with jets, because you get 2 additional quite strong attackers, which leaves your opponent with some new questions like (do I rather want to shoor this eJet who is in my face or rather shoot this 5 spaces away DT and leave the jet alone) which MAY lead to some non vader competitive lists. It is also worth noticing, that they don't require any CCs, that you normally wouldn't inlcude in order to be effective, which leaves you space for some other nasty stuff.
I am not saying, that they will be autoincludes, but it's defiinetly too soon to judge them.
