It will be interesting to see if those cases result in many deaths. Typically when viruses mutate they become less deadly, so there's a chance these new cases won't have nearly as negative an outcome as the previous waves. The data is still coming in, but initial numbers look like a negligible amount of deaths compared to their historical numbers.
Evidence suggests Delta may actually be slightly more lethal, all else being equal. But all is not equal, a lot of the most vulnerable folks are either dead or vaccinated now.
