This morning I had a male Wilson's Warbler in a garden in our backyard. I think of any October Wilson's as latish. Interestingly e-bird shows about 30 records this October in NE Illinois. This compares to only one record last October in the same region. Going back to 2010 there are generally fewer than 10 October records each year, so this is an unusual year. A quick check of some other warblers that are largely gone by October doesn't suggest to me that the large number of October Wilson's this year is echoed in other warblers.
