I was just on the Eroica website looking for news of Eroica California and Eroica Hispana. However, they are both MIA, suggesting that they will not be happening. This is unfortunate, because I was planning on riding both of those. That said, I noted that the Nova Eroica Switzerland on 15 June has the following language: "The rich program proposed will offer you an incomparable timeless break in pure Eroica style thanks to its Festival, its gastronomic treasures and for some activities for vintage bikes lovers". Not sure if that's enough to warrant adding it to your list since they don't explain what "some activities" means.
