will never happen. PCIe needs very high quality wiring, GPIO would not work 3 inches from the pin.

The SOC is almost guaranteed to have USB 2.0 and 3.0 built in. I donāt think there is an external USB controller.
They have a dedicated chip for USB though. Thatās what attached to PCIE x1 lane. I could be mistaken though
[Edit]
āUSB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four portsā

Very disappointing. I would have gone with a better SOC.
That would probably increase the price. They are trying to cut corners to make it as cheap as it is. But I donāt know all of the details. Maybe there were other reason as to why they went with this soc.

Yeah, they are committed to keeping the base price at thirty-five bucks, and release new faster hardware when it can meet that pricepoint. Got to admire their dedication, no price inflation there.

They need a pi 4 ultra version
I donāt like that they replaced the full-size HDMI port with 2 micro HDMI ports. They are far more prone to breakage than a standard HDMI ports in my experience. (Iāve owned 3 devices with micro HDMI and theyāve all broke) I think most people will still only use a single display (if they use one at all). If I were in charge, I would have replaced one of the USB Type-A ports with a type-C and passed the second display through it. I also question the wisdom of trying to drive two displays with such a low-power device, but maybe the new SoC really is that much beefier. I guess weāll see once some early reviewers look at it.

Dual microHDMI does seem strange at first. But, think of some of the possible fun projects:
- Dual screen signage
- Clamshell dual screen Pi tablet
- Battleship game over one pi with two screens

Dual screen personal computer. Honestly if it werenāt for X86/Windows specific software I need, I could easily switch to RPI. In few more years maybe weāll see exposed x4+ PCIE lanes and then external GPU on RPI might be a real thing.
Really fucking tempted to do this.
Does HDMI support MST?
I donāt think HDMI supports daisy chain. Unless MST is something different.
Multi Stream Transport
Kinda like daisy chain, but not really.
Iām glad this came out. Iām going to use it to run a media player for Prime, Netflix, Hulu, and Parsec for game streaming.
Might be nice to use something like this to make a low powered laptop alternative with game streaming focus on home networkā¦maybe get a nice Bluetooth mech keyboard and wireless mouse. Since it can do h.265ā¦

It would be very cool if say Google released an Android, Android TV and/or ChromeOS image for it. It is more than powerful enough and makes sense as a Dev and testing platform for Apps.
There is a github Project for ChromiumOS on the Pi3+. That worked decently well. Iām sure thereāll be builds for the pi4 soon.
There are also several Lineage OS builds for the pi3. None official but they work decently well.

I would have been excited for this in the past, but with x86 options popping up I have less excitement for this as honestly I just havenāt had a good experience with things being ported over to ARM. There are some very purpose built projects for the Pi that are good, but outside of those use-cases I dread the thought of trying to find tutorials that apply to the ported version of the OS- for example web hosting.
Iām surprised nobody has mentioned Vulkan yet. The new chip has a open source Vulkan driver in development. When using the GPU for compute intensive tasks the RPi would make quite the machine for computer vision and small AI based projects.

I have ran LAMP and BAMP stacks on model 2s. And sometimes ran it with NGNIX . Seems to do alright for quick and dirty stuff.
I wouldnāt run it in a production environment but I wouldnāt do it with an x86 Dev board either.

RPIs are actually very reliable, except for the MMC storage. If you have some sort of embedded or limited use that wonāt be constrained by their very poor performance, and plug in a USB drive, they do a great job.
