There won't be a hardware fix, you can't patch CPUs (aside from microcode which is just more software). Since this is a pretty fundamental issue wit how certain things work, yes, you'll have to wait for a new generation, and I couldn't expect anything in less than a year at the absolute earliest. It's a multi-year process from design to tape-out and fabrication. Honestly, I'm not sure how far back in the design process fixing this will take, it is something that can be added in as permanent microcode after fabrication/during packaging? Can current designs be "patched" before moving on to tape out? Do we need to go back to square one and rethink a couple key premises? I don't know. But it's not quick.
