Talbot's Return Definite?

The Penguins announced this afternoon that they've re-assigned forward, Mark Letestu to their AHL affiliate in WB / S.

Does this mean Talbot is more certain of his return and is likely to be in the lineup Thursday against the Ottawa Senators? This is a pretty telling sign to me, but we'll just have to wait until Thursday (or until the Pens make another announcement).
