Now waiting for the EL-5 and the EL-x0. The EL-100 already exists.
Good point on naming. I was wondering where they might be headed, EL-5 and EL-10 seem like a good start to complete the line-up
EL-1: new flagship line, $1100
EL-5: 600-series replacement, $600
EL-10: 430EX replacement, $300
EL-100: existing, $150
I said this on the other post, but I'll crosspost my thoughts here in this thread:
So unfortunately I guess Canon saw that with the Profoto A1, people were willing to pay $1000 for a flash

Unfortunate because I see this as a big update over my 600EX-RT, but will definitely try one out through Canon CPS and see if I decide it's worth the investment. I'm sure the pandemic may have upped the price with how delayed this thing was anyway. I wish it had more power output for a higher price, though. You can buy two Paul C Buff Einsteins or one and an external battery for the price of this, which is a lot more power and makes this a bit frustrating. But it's definitely a new line above the 600, so I can understand this is aimed at 1DX customers.
Looks like the new LP-EL battery is almost identical to the LP-E6 but is slightly longer and hangs off the LP-E6 charger. Should be enough to not confuse the batteries with LP-E6, but I'm sure I will anyway.
Nice that it includes the LP-E6 charger. I already have 3 but it I do enjoy having more to be able to charge more camera batteries anyway.
In one video I was pretty pleasantly surprised by the output of the modeling lights, they seemed to be pretty effective and directional even inside of a softbox. Also seems like it will be a nice autofocus assist, since you can turn it on and off just by double tapping the shutter button.
Canon hasn't mentioned it yet, but I get the impression the modeling lights could work well for video in low light, especially since they have adjustable color temperature. 3 hours runtime is somewhat short, but would be fine with a few batteries for long events.
I still think the biggest single thing for me is the 1/8192 power level. I shoot a lot of low light and long exposure portraiture where often I end up avoiding flash altogether to be able to see ambient light. I can see this being super useful for F/1.2 portraits in low light where you just want to add a pop to the face of your subject and some catch light in the eyes. Previously I've used cellphone flashlights on low power for some of these uses, but a flash in a softbox or umbrella would he endlessly better. Even just the modeling light would work great for those uses.
