I'm also seeing a sharp rise in the First Page bid across my account.
I'm also seeing this in my account & on keywords that are totally related to the search.
For example the name of our business is "Some Great Widget". Searches for "some widget" & "great widget" (exactly related to the business & ad) have doubled or tripled for first page placement.
AdWords is becoming very frustrating for a small business.
