These two were tied up in the chain of evidence that led to his conviction, so depending on what gets tossed he has a chance here. Now he did admit that at one time he was DPR and that he had resumed work under the alias so he's probably not going to get everything overturned. But his defense was that someone else associated possibly with MTGOX was the mastermind framing him more recently.
So what's intriguing here is that one of the investigators was doing some shenanigams with MTGOX accounts and was involved in seizing MTGOX assets. Since MT GOX started having liquidity problems right during this investigation of Silk road, it really makes you wonder if this is where some of those missing assets went.
Furthermore the agents appear to have done things as their shenanigans came to light to obfuscate the trail back to them. This is not too far afield from ulricht's claim that someone was framing him, asking him to step in as DPR, and putting keys on his computer.
It actually seems it's not far fetched to imagine Ulricht was telling the truth about having relinquished DPR that someone suddenly invited him back into the game as the FBI closed in. Perhaps there's some grains of truth in there somewhere. e.g. maybe one of the agents did add his bitcoin keys to Urichts computers.
Given those sorts of conjectures it seems very reasonable he should get a new trial. He's guilty by his own admission, but maybe not guilty of everything he's charged with.
