Some updates from C4Eva about the Slim 0225 CFW that will directly be 'LT 2.0' with XGD3 support (the new disc format MS will introduce with the new fall dashboard, and currently being tested by the Beta Preview Dashboard). He also said something about the x360key and apparently there's more to come...

From c4evaspeaks.com:

[G***] c4eva has there been a roadblock on 0225 progress?
