Great news. RPI 4 is out.
Raspberry Pi Blog - News, Announcements, and Ideas
Several serious (long time requested) improvements have been introduced:
* separated ethernet/USB
* BT 5.0
* USB3.0
* up2 4G RAM
* and more
Enjoy.

As usual, I'll wait 2-3 months to let the dust settle.
They slightly changed the layout. New cases need to become available.

Need any more dust to settle ;-) ?
Ordered 2GB version today. Including case.

Yep.
Actually "dust" refers to firmware and driver issues.
Usually it takes a while to get the issues under control. Usually even more then 2-3 months.
...then all the audio OSes need to adapt properly.
I'll probably get onboard around September.
Wow, they kept that under wraps pretty well. Had not heard of an imminent release of the Pi 4, but am definitely excited about it.
The increase in processing power, available RAM (1, 2,and 4 GB options now exist!) splitting of USB and ethernet, etc. will all make this very competitive with other ARM based SBCs and even with some low end (e.g. Kaby Lake, Gemini Lake) Intel based mini-PCs.
Allowing some time for things to shake out and the Debian Buster based OS to become available is not a bad idea, but why wait? Start having fun now!

I found some benchmarks run on the Pi 4, that compare it to previous Pi versions, here:

Thanks, interesting article.
The A72 core and separating ethernet and usb (finally) appear to make a big difference in speed.
I expect heatsink companies to start working on thermal solutions, looks like you can't throw on a little heatsink and put in a small case anymore.

You can still do that. The SOC will simply throttle (reduce clock speed) when it reaches some high temperature. You can also set the CPU clock to be always slow, although this and the Pi's own throttling will reduce processing power.
I would have been nice if they took the route of e.g. the Odroid N2, where the SOC is on the bottom where not much else is found, and the whole SBC comes premounted on a large heat sink:
ODROID-N2 — ameriDroid

The GPIO benchmark shows a nice increase.
I'm wondering if the new soc would allow for higher I2S frequencies.
With the great USB and ethernet performance it's gonna be a nice (LMS) server.
Especially if booted from USB-SSD and data also put on SSD. All that looks really promising.
The more you look at the device the more you're tempted to push the "order-now" button.

Where is the problem ? Either you take a cable or wait for the z-shaped adapter that will come in a few days...
Another review
Raspberry Pi 4 Review: The New Gold Standard for Single-Board Computing - Tom's Hardware
Looks like if you run off a usb3 stick you'll get a nice bump in performance.
I did see that it throttles if temps get too high, but I don't want it to throttle if I'm getting this for the better performance.
But in real life, for the kind of stuff I'd use if for, may not have a heat problem, my pi3's don't get very warm even in a case.
I really don't want to have to use a fan, but I also know that just moving a little air makes a big difference in getting heat out.

This seller may soon have a Pi4 version (once my Pi4 arrives I will check to see if it will fit this clamshell heatsink I have on a 3B+)
I currently have the passive unit.

One of the best Pi cases that I know, and that helps with thermal management, is made by FLIRC:
https://flirc.tv/more/raspberry-pi-case
The top of the case has a large block that sticks down and contacts the top of the SOC via a thermal pad. Heat is then dissipated via the case. WiFi performance seems unaffected.
If they offer a Pi4 version of the case I would buy it.
I think unless you are maxxing out the Pi on computer-intensive tasks you will not have a problem. If you need something with more CPU power, get a mini PC instead of an ARM board and be prepared to spend much more. YGWYPF

Some background. I running home automation software (home assistant) and node red on a pi. When I used the same pi3 for both, there was noticeable lag. I moved node red to its own pi3 and that was much better. Some lag still, but I also have alexa in the mix and I figure that alexa adds some latency too.
I figure I'll upgrade at least one of them to a pi4, and see how that goes.
Most of the time these pi's are doing very little, its just that's its nice to a fast response when you ask alexa to do something lol.
Based on this use case, yeah I don't really expect the pi4 to get very hot.
But I don't like my electronics to get hot, the 80C throttle temp is MUCH hotter than I would like to see, ideally I can keep temps under 50C.
BTW, flirc has pi4 cased on presale now.
@DRONE7
Thanks for the link, nice case too. I think I like the flirc better, especially at the presale price, but I'm sure either would work.
