Opus hasn't yet gotten an update from 3 to 3.5, and if you line up the benchmarks, the Sonnet "3.5 New" model seems to beat it everywhere.
I think they originally announced that Opus would get a 3.5 update, but with every product update they are doing I'm doubting it more and more. It seems like their strategy is to beat the competition on a smaller model that they can train/tune more nimbly and pair it with outside-the-model product features, and it honestly seems to be working.
