Looks like the Metric Halo 3d Upgrade is just about to drop

Just saw this posted to their Facebook page: 

New 3d Master Board hardware with the following:

USB-C for USB connectivity
▪audio transport is implemented in HW - there is no software involvement
2 MHLink Gigabit Ethernet ports
▪ these work for both audio and data transport
▪ audio transport is implemented in HW - there is no software involvement
Word-clock in and out
EdgeBus card slot (for flexible additional I/O)
New clocking circuit for better clock accuracy and jitter performance
Auto-clock rate detection for external clocks
New digital power supply design for improved clock performance
Support for !all! existing boxes (ULN-8, LIO-8, 2882, ULN-2)

MH Multicore Audio Network On a Chip (ANOC) with
▪ Instantiable +DSP processing core with massive system RAM (1 Gigabyte)
▪ Custom dedicated processing cores per chip *:
128 channel by 64 bus 192k Mixer core with fully interpolated gains
▪ 1024 slot audio router core (@192k)
▪ 1024 channel Peak/VU/RMS meter core
Custom I/O processing cores:
▪ AES I/O core I2S I/O core
▪ SPDIF I/O core ADAT I/O core
▪ TOSLink I/O core SMPTE I/O core
▪ MIDI I/O core MADI I/O core
▪ Custom communication cores:
▪ USB Audio transport core
▪ MHLink Audio transport cores
▪ GigE packet router core

Firmware for the 3d Master Board:
◦ Full support for all of the front panels
◦ Full support for USB MIDI Class
◦ Full support for USB Audio Class 2
◦ Full support for USB Control of connected box
◦ Full support for MHLink Direct Audio + Control
◦ Full support for AES/SPDIF/TOSLINK/ADAT/SMPTE
◦ Full support for all existing analog boards
◦ Full support for all digital I/O boards
◦ Full support for all EdgeBus cards
◦ Full support for all Firmware update (over USB or Ethernet)
◦ All +DSP plugins ported to new platform
• A variety of new EdgeBus card Hardware modules in addition to the one to replace AES/SPDIF on 2882/ULN-2

New MHLink Direct driver:
◦ Allows communication with boxes via Ethernet
◦ Provides one audio device for all boxes connected together via MHLink (up to 128 channels of I/O @ 192k)
• New Mio Console 3d
◦ Revamped UI
◦ 64-bit Portable App
◦ All +DSP plugins ported to 64-bit
◦ Manages MHLink Domains (groups of boxes connected together via MHLink)
▪ one clock domain (all boxes slave from master)
▪ one audio driver (all channels available via one driver)
▪ one consolidated mixer (all inputs and outputs available to the mixer)
▪ all channels time-aligned
▪ no additional cabling requirements between boxes (just an MHLink cable)
Consolidated mixer supports up to 128 inputs and 64 busses
@192k across all the boxes in a domain
◦ Automagically manages routing within the domain (no user-level box-to-box routing required)
◦ Automagically manages resource allocation between boxes in the domain
◦ Automatically manages clocking between boxes in the domain
◦ Simplified routing model relative to 2d (even for one box)

• Lots of usability enhancements in the mixer
The processing going on in the "Custom dedicated processing cores" (marked with a *) above is approximately equivalent to the processing power of 30 2d DSPs. It is dedicated processing, so it can’t be used for plugins, but it is processing that has to be implemented on the DSP in 2d, and it requires no instantiable DSP power in 3d.
The RAM available to the instantiable +DSP core (1 GB) is more than 2500x the RAM available in 2d (384 kB); this means that running out of memory for delays or reverbs simply won’t happen on 3d.
In multibox systems, the instantiable processing is distributed over the processors in all the boxes, so adding more boxes adds more processing.
