I would just like to say something about the specs required in order to design anything in engine are insanely high.
Even just to make a simple mobile app or 2d platformer its overkill.
Also you have lost a huge number of skilled developers due to these Hardware Requirements.Only the Guys with the Biggest and Bestest get in the door leaving the rest of us out in the cold.
Tbh i will probably just use Unity3d for most everything over resource hungry Engine.
I think if you would like to see alot more people making good use of Engine then Please consider some kind of slipstream lower-end spec development environment.
Just remember that we’re Average Joe with computers that have 2-4 Core CPU’s , 2-3GB Ram , GPU which can play UT2k4 beautifully and Ut3 on low - med settings … 200+ HDD space.
Not Pixar or Weta with 128Gb Ram $10,000 GPU and enough HDD to spare the world over.
…And more Cores then an Orchard.
Sorry for my bluntness , but i feel needed to be said. Also will be one reason why you will not get so many subscriptions … simply because only a minority have Ninja Kickass Computers and therefore only they can use the new studio.
Pitty cause i for one am very interested in getting on board with .
There is a way surely… where you can make it work for the majority …
One idea is the development process be lower polly then once the developer is happy with it they can upload it to your super computers for rendering and binaires 
Forgot to mention that we also have more Bandwidth these days and can afford to upload 1-2GB as well.
Thanks.
