Heat and power increase are harsh.
Ordered! Cheaper (and faster) to have it shipped from the UK than from a US seller!
Strangely enough, one of the RPi2s I bought last week was DOA (wouldn't boot off a card that worked on an identical Pi2; red/green LEDs just stayed solid).. So, how convenient!
That's not really surprising, given they're made in the UK by a UK company with UK-based distributors. :)

It says it is shipping out with the 2A PSU while the rpi website recommends that the pi3 uses a 2.5A psu. Any reason?
> Any reason?
Yes. The full recommendation reads "This time round, we’re recommending a 2.5A adapter if you want to connect power-hungry USB devices to the Raspberry Pi."
So I guess the assumption is the average person won't connect power-hungry USB devices to their Pi 3.

Probably a stupid question, I don't know much about this stuff. Is there any reason not to just use a 2.5A even if you're not connecting power-hungry USB devices? If it doesn't cost significantly more and it doesn't hurt to use 2.5 anyway, it's something I'd rather not have to worry about.
Feel free. It'll only draw as much current as it needs. The rating on the power supply is just an upper bound of what it can (theoretically) provide.

That makes sense though I don't see a 2.5A adapter to order separately on their website (because I might be needing one later).

I have several of these, they are 2.5A and good quality.

Wouldn't the more common use-case for power-hungry usb devices be to have a powered hub to drive them? Then you don't have to worry about browning-out the RPi itself, though of course the cable clutter is worse.
We will be sourcing the 2.5A power supply but it really is only necessary for very power hungry setups!
Would two webcams quality for that?
That would be pushing it for powering through just the RPi. Webcams are typically rated for 500mA each and the RPi has been running around 700mA usage. So with the recommended increase, I'd wager their power usage may have gone up to 900+mA.
