Yes, very realistic and expected that the government could cancel the warrants AND deem the sps paid in full. This will come as a "negotiated" concession between fhfa and treasury, in lie of treasury returning 80+ Billion in excess takings (ie. $180B in and $300B out) ... or about 80B more than normalized.
So absolutely yes.
Anyone, that says there is no chance or little chance has an agenda or not very bright. Keep in mind Ack'man .& Pags have agendas and narratives.
