Yes, it will but also looking at options for a bare essential model as well in addition to the full featured one previewed earlier - so basically 2 models to choose from
Basic model:
Requires external 3.3V and 1.2V supplies as shown
Empty board: USD 45
Only IC loaded: USD 85
Fully loaded module: TBA
Availability: TBA

Nice - I recognize the layout architecture!
Schema? Teflon? Input for external oscillator (MCK1?)?

It seems in the end I'll be considering the full feature model unassembled with chip preloaded, if there will be at least minor options for HW config via jumpers (bit depth, sampling frequency). Count me in on one if these will be the case 🙂
Thanks!
Schema, BOM and support information provided for this basic version (AKA102B). Prices are for FR4 boards only. Teflon/Rogers option ~$120 extra. All options will be listed when design is ready.
On-board XO can be 9x14mm, 7x5mm or 2.5x2mm types. Suits Crystek CCHD957 and NDK XOs. U.FL coax for external clock if preferred
Full featured models will be rolled out as fully assembled OEM modules only. Sorry, no options for DIY assembly
Sounds great all around to me. Without a controller, what comes out of the board?
Would be nice with some onboard strapping possibilities.

Without a controller only i2s output, could always send that to a hardware DIT of your choice for SPDIF conversion if that's your preference. I read the datasheet a week or so ago and don't have it in front of me, but I believe that you can configure whether it is master or slave i2s device.
I like the line level input. The ADC card can be reused with many different inputs. Maybe you can design input cards as well?
I would prefer to have on board power regulators (SMPS and very good traditional regulators), since these are difficult to design. Maybe a separate card for this?
The Raspberry Pi can be used to control the ADC through I2C. There is a Python package for reading and writing to I2C.

ESS Products - ADC
I have tried that maybe a year ago. I even did an NDA, but received nothing. We will need documentation in order to control the ADC. Acko can you talk to ESS so that forum members get access to manuals?

Suitable cards can be designed as we go along but the first module needed is a matching buffer to drive the ADC - TBA
There are several well known psu designs already. You can also use 3-term types with connections as shown. Makes it very straightforward and you can experiment with different types rather than a fixed on-board one

You should also consider battery psu especially if you are shooting for the best when recording or digital mastering
"Sample rates can be selected in hardware mode: 48k, 96k, 192k and 384k"...
How is this done?
