The press release leads with this epic title:
The subtitle may have been better still:

Like all statistics these too can be misleading, but it's better to talk with numbers than with gut feelings.
This beautiful chart by Jan T. Sott shows performance on the Kraken benchmark, for browsers from Firefox 3.5 to Chrome 23, on the same hardware. Keep in mind, that it doesn't show the huge jump in performance that Chrome brought on release from the then-current browser versions. If you want to see what's happenned since Chrome 23 (December 2012), you can do worse than Mozilla's arewefastyet.com benchmark site.

Everyone knows NPM is exploding. Over the last year it has grown to the tune of 10x in packages and traffic.
Observe how NPM is the only one with an accellerating rate of increase in packages. By our estimation, by February 2015 NPM will have caught up with Rubygems and Maven Central.
Besides the 55,000+ packages in NPM, there is an additional 6000+ front-end packages in Bower, which is also increasing at dizzying speeds.
Another marker of the ecosystem is the number of languages that compile to JS.
What next for JS?
Undeniably, the enterprises are coming. A rich startup ecosystem is growing around node.js, and big companies like Yahoo, PayPal, and LinkedIn have invested a lot of resources into adopting it internally. Besides the web giants, node.js seems to be catching on in some companies you might not expect, like Walmart:
"I'm ready to certify Node 0.10.22 as 'Walmart Black Friday Ready'. If you're bigger than that it's your problem." - @eranhammer #nodesummit— Laurie Voss (@seldo2) December 3, 2013
A few of the most exciting projects and events in this space: Nodebots, Nodecopter, Tessel.io, Espruino, Device.js as well as applications like heimcontrol.js and Google Coder for Raspberry Pi. These are just a few of the fascinating projects we've seen pop up over the last few months, there is certainly a lot more to come.
By means of a conclusion
How the pieces will align and what the medium-term result will be is anyone's guess, but exciting times are definitely ahead, and the only way is up.
