I'm sure you can't fail to have seen the specs of the new Pi 3 model B, as launched today.
One interesting feature that hasn't had much attention yet, is mentioned here :
"A minor change, which will help those who use attach drives to the Pi, will be the ability for the Pi 3 to boot directly from a USB-attached hard or pen drive - rather than having to boot from an SD card. Similarly Pi 3 will also support booting from a network-attached file system, using PXE, without the need for boot data on an SD card - something Upton forsees being useful for boards used for factory automation."

I watched the launch videos / livestreams / conferences etc this morning with interest, largely dismissing any need to have a Pi 3 as I've several Pi 2 and B+ doing useful things, which seem fast enough for my needs.
I caved in around 11am and ordered a Pi3 kit from Pimoroni
It'll replace my Pi 2 desktop; will be interesting to see how much faster it is; eg web browsing is acceptable on the Pi 2 if you're not in a hurry. GIMP graphics package loads faster on the Pi 2 than on my Windows PC!
