Good deal for both sides.
I remain in my belief that there is zero urgency to trade either Korpi or Elvis. Neither has been consistent enough to be the #1. Both have had periods of horrible play (Elvis with the worse stretch), and both have had periods of dominating play (Once again Elvis with the best stretch). Both have similar issues (both need starters minutes to perform, both give up a fair number of soft goals) and strengths. There is no need to rush this decision.
We have a whole other year with both under contract (assuming Elvis gets a similar deal) before the expansion draft. That's when the decision needs to be made on who needs to go via trade. Until then keep and develop both because I think we're in decent hands with either one.
