It will be whatever the latest node is at completion, so most likely Intel 3 or Intel 20A [1]. It was Pat Gelsinger's pledge to get Intel's node roadmap back on track when he joined as CEO just under 2 years ago. From what they've been submitting papers wise to industry forums, IEEE Synopsium and the like, they're on track to deliver 20A by 2025. I recommend following the progress of Intel's new "Intel Foundry Services" business segment.
