Not really. That pic was already after price cuts and storage bump. The iPhone SE was released March 2016 so there shouldn't be an iPhone 8/X on the lineup. Heck, there shouldn't even be an iPhone 7. Mind, it was actually $250 cheaper than the 6s with same A9/2GB which for Apple was pretty unheard of. Granted, it did have lower base storage.
Iirc, launch pricing for the SE was $399/16GB and $499/64GB (I bought the 64GB for my mom). Although the 5s was selling for $449 prior, that's because the lineup at the time was $449 5s, $549 6 and $649 6s.
I can see $50 lower price for SE 2 compared to iPhone 8 but I don't expect any drastic price reductions. Besides, as long as the SE 2 is better than the iPhone 8 it's replacing, it doesn't really *need* to be cheaper for it to make sense. Of course, I'd be happy if it was cheaper but I'm content with a CPU and RAM bump at same price as iPhone 8.
