I don't think he's struggling with anything apart from a lack of enthusiasm really. The guy is the sickest engineer to ever make dnb, his new tunes are still incredibly loud and sub heavy as per his trademark, it's the ideas that are lacking. Severely by his standards.
^ I agree, if he is struggling with making a switch to digital production then he should just stay analogue - everyone knows that old Dillinja tunes STILL piss all over anything else in terms of fatness and impact
One thing that could explain all these huge names' production going down the toilet is that they're just going deaf? I dunno... I've always thought it's a possibility. They've spent much of their time in clubs listening to deafening music and well maybe they just can't hear bass anymore.
DJ Hype played a tune at Hideout festival and so did Prophecy that is supposedly a new Dillinja tune (a friend of Prophecy told me) and it is seriously fat, just like his old stuff so maybe he has got a few things up his sleeve
