Yes, indeed, this is great news! WFK!
I just compared it to the E9. Same length case. E12 has 2.5s burn time vs 3s for E9. Both have sustainer portion of curve at ~10N. Both are ~36g of propellant (ie, no mailing).
The key diff is that the E12 has a 33N initial thrust spike vs 20N for the E9. So the E12 is very much like a longer burning D12 with a similar initial kick.
I'm really looking forward to getting my hands on some of these! This is really exciting news.
