Razer Core V2 Announced with TI83 Controller and Dedicated Expansion I/O Solution
Here's my guess of the dual-TB3 controller setup. The main board for the Razer Core V1 has the Expansion I/O go through the single DSL6540 TB3 controller shared with PCIe slot. The dual setup has PCIe slot use one TB3 Controller while a second TB3 Controller handle the Expansion I/O. Both travel through a single USB-C/Thunderbolt port.
I think it's cool for Razer to continue with Core, this only shows that eGPU has everything to blast! But it is the high price that Razer charges for eGPU.

No Vega support, second Thunderbolt port is still a question, 500$ ... worth it?
@chaosmage, this enclosure is not worth $500 (imho) unless they have either a second thunderbolt port or a second USB 3.1 port to attach two cables to your notebook. Then they can separate I/O and eGPU traffic.
Consider it's value against other enclosures in the Buyer Guide. Like:
- US$527 Aorus Gaming Box (includes a GTX1070) , on Amazon in AS NEW - Item is in original packaging, but packaging has damage condition. A miniture enclosure including a GTX1070. With a GTX1070 in this enclosure it weighs less than half of what a Core V2 without a video card weighs.
- US$490 Asus XG Station 2 that does have a twin cable approach to separate I/O and eGPU traffic. It has a Thunderbolt 3 and USB-B port for that.
- US$249 AKiTiO Node - no frills, gives plenty of leftover $$ to host your fast storage on it's own separate port.
Not sure why there is concern / confusion about the dual controllers and why we keep talking about one TB3 cable. This is really two devices in one: a PCIe slot for eGPU built around one TB3 controller and one TB3 port, and (effectively) a USB hub built around another TB3 controller (TB3 has a USB compatibility layer to deal with stuff like that). Seems perfectly reasonable to me. Although that is likely part of the reason for the high cost. Thunderbolt 3 controllers are expensive.

Razer don't need 2 Thunderbolt cables. They can simply daisy chain one TB3 controller with another.
Each TB3 cable is Intel limited to 22Gbps of PCIe traffic. Daisy chaining TB3 devices simply extends that chain but the same limitation applies.

All TB3 enclosures with I/O ports are already using their TB3 controller's onboard USB 3.1 controller. A second TB3 controller is unnecessary nor makes much sense unless a second TB3 cable is used. That's because one TB3 controller encodes data for transfer down one TB3 cable.
https://www.anandtech.com/show/11945/razer-launches-core-v2-tb3-egfx-enclosure-two-thunderbolt-3-controllers explains the "dual-TB3" controllers Razer Core V2 marketting.
With its second generation Razer Core, the company uses two dual-port Intel DSL6540 ICs coupled with the newer TI TPS65983 controllers. The primary TB3 controller now uses all four PCIe lanes to connect the GPU to the host PC. The secondary TB3 controller is connected to the primary one using the downstream TB3 port of the primary DSL6540 (essentially creating an internal daisy chain) and uses its PCIe lanes for the GbE and the USB controllers (basically, the DSL6540 is used like a PCIe switch). In this scenario, the GPU always gets a priority and the traffic from the other clients is always routed properly. As a bonus, the Core v2 does not have compatibility problems because they now use the newer TI TPS65983 controller.
As a DSL6540 has separate PCIe buses for the PCIe and USB controllers as shown here it is not clear why Razer then felt the need to separate thoses buses again by using another DSL6540. Maybe for marketting only . . . which will open the product up for returns/chargebacks for dubious "separate lanes for eGPU and I/O" since eGPU and I/O traffic terminates at one x4 3.0 TB3 PCIe bus.

Is this better than the Mantiz venus? I have order the Mantiz but for the Portugal with the taxes i could go for this from razer in germany, no taxes....
@Evangelista, you can see a comparison, including EU pricing, of current TB3 enclosures at:
The HP Omen Accelerator at €299 is the bargain of the bunch.
