If Strahi is only at Yale for the fall, he could still be teaching 1L Property next year (if they move it to Winter/Spring). Thats good. And Gersen could still teach his half of 1L torts if they move that to Fall/Winter to replace Property.
And yes, I'm sure you incoming students can email Dean Richardson to ask. We current students may be a little tentative on doing that, for fear that she'll LawAnnounce our email, but the incoming 1Ls don't really have to worry about that.
