I got the "until June" email, not the profile update one.
It was a tough choice: I had about $15 worth last year that I couldn't use by the usual deadline. So, whether to use another $10 of this year's to get 1000 Hilton points (which aren't worth much) or lose about $11 (75% of the $15). I took the Hilton points, since all the other rewards are devaluing too.
