The Raspberry Pi Blog announces:
Raspberry Pi 3 Model B+ is now on sale now for $35, featuring:
- 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU
- Dual-band 802.11ac wireless LAN and Bluetooth 4.2
- Faster Ethernet (Gigabit Ethernet over USB 2.0)
- Power-over-Ethernet support (with separate PoE HAT)
- Improved PXE network and USB mass-storage booting
- Improved thermal management
Alongside a 200MHz increase in peak CPU clock frequency we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.

FAQs:
Now I am left to wonder how many amps the power supply wall wart needs to be.

I was just thinking the same thing, the press release is missing:
I like the original Pi, it was a great educational toy, but it's remained just that. If you want to actually build something that you can rely on, get a BBB (low-power) or an ODroid (high-power) or something similar. The first time I looked at the ODroid schematics I was astounded, everything the Pi does wrong is done right in the ODroid.

What does that mean? There are plenty of USB devices that are self-powered. Does this mean that Rasberry Pi is so broken that it will suck power from USB hub, even when it has its own power source??? It should be just using the data lines!

I've got dozens of micro usb power supplies, from 500mA to 3A. Any of them work fine with the Pi in my experience. I regularly power it from my laptop USB ports too. Switching to a barrel jack would be incredibly inconvenient as I'd have to buy all new plugs for all of my Pis. I also have a Pi running from the USB jack on my router, while if they switched to a barrel jack I'd have to run an extension cord to get more free outlets. Or, more likely, if they switched to barrel jacks I'd be spending hours sitting there splicing USB ends onto them. USB is perfect for this use case. The only thing I've ever seen a barrel jack do better than a USB one is bursting into flames, but if that's what you're after you might need a bit more than 5V too ;)
Yeah, probably agree with you on this one, although it depends on the price. The Pi certainly is not designed to be a file server or anything, and I can't think of any times when the bandwidth or latency of any of mine have been an issue. If adding a real Ethernet port is gonna cost an extra $5, it's not worth it to me.
Never had this problem. I run a Pi with a USB webcam and another USB used just to suck power for some fans, and that's the one plugged into the USB port on my router, and it's been running for about a year with no issues. I suppose you'd need a powered port if you've got some seriously high powered peripherals, but as far as I can tell the Pi is perfectly capable of delivering the 500mA required by the USB spec. If your device requires more, it ought to come with a way to get that power.
So that if anything goes wrong with the memory, the entire board is trash? Any flash memory has a limited lifespan, so soldering that crap to the board is just a form of planned obsolescence. I prefer my computing devices to have as many serviceable parts as possible. Plus, soldered memory means non-expandable memory. Some of my Pis run 8GB cards and don't even need that much; others have 64GB card that still aren't quite sufficient. So even if you include onboard memory, you still have to have ports for additional external memory. Which means you'd be needlessly increasing the price for anyone who needs more memory, possibly overcharging anyone who needs less memory, and making life more difficult for people who try to use both.
Also keep in mind that the Pi is the lowest common denominator for these kinds of devices. It's the Ubuntu of single board computers. The main advantage it has is convenience, and convenience is king. For any specific needs, you can probably find a Pi-alike board that would do the job better; but if you're going to be using it for something different every week, the Pi is an excellent cheap and safe choice.

and both the bb and the odroid are more open, IIRC
