I wanted to ask now because if there is no chance or next to no chance seeing an upgrade from the developers then someone in the community might consider trying to upgrade. I had tinkered around with no success but then again I'm not much of a programmer.
I felt this belongs here since I think it's quite the important question.
Also before we finish up we know most the development happens in the East. Would the developers in the West consider actually doing this themselves if the East had no want to do the upgrades? Mainly because the entire client is open source.

Upgrading from v2 to v3
In short, it’s SUPER easy. A lot has changed under the hood but thankfully for you guys and gals not so much has changed with regards to the API. For those of you coming from v2 we encourage you to jump on board. Just like sunshine and beer, life is better with v3! The air is sweeter, the grass is greener! (The grass is also anti-aliased).
We also added a deprecation file so that any object that no longer exists will return its new alternative and also warn you with a console warning. This means things will mostly just work but you will be made aware if you are trying to do something the ‘old’ way.
Anything else should be covered in the docs and examples. If we have missed something make sure to give us a poke.
Some of the benefits are quite insane and I wonder if some of these would fix the slow down people are having between map transfers etc.
New Loader
That’s right! A shiny new loader! Created by Pixi.js team member Chad. There are lots of advantages to this new loader. Pluggable and extensible parsing and caching? Yessir! Better modern xhr support? You bet! Add to that a more fluent api, better progress reporting, more insight into the data loaded and you can start to see how cool this new loader is! Who’d have thought the humble loader could be so exhilarating!
And of course one the biggest:
New WebGL Renderer
Marvellously, WebGL penetration is pretty high these days. It’s also on mobiles now too. This makes the WebGL renderer increasingly the main event now for Pixi.js v3. To reflect this we recoded the WebGL side of things to be more efficient. It can still throw TONNES of stuff at the screen but on top of that it’s also a lot smarter when it comes to how it switches render modes. This new WebGL base will make it easy to add new features as little v3 grows up.
