[Development] Question about Qt's future

[cincirin]

Sorry for re-open this topic, but as someone else already pointed out, 
what do you think about the Unreal engine guys to abandon the unreal 
script which was used until now for many years ?
To quote some comments:
"In the past, gameplay code existed in UnrealScript. UnrealScript is the 
scripting language which forms the core of current community mods, and 
much of the gameplay code of all previous Unreal Engine titles.
However, UnrealScript is being removed.
In its place, the engine will be 100% C++, and highly optimized."

Also I'm curios why Android xml files are good for design the UI, but 
"old" QtDesigner ui (xml) files seems to be deprecated in favor of qml.

Best regards,
