"Announces" is a big word. They are disclosing a product that will come out in almost a year from now. They are doing so to make sure that people remember that Intel exists when AMD launches Zen 2 in just two days, making sure they have it in the corners of their minds that Intel will have something new as well at some point not that long into the future as well. Even if it's not anytime soon and there's nothing even suggesting there will be any gains in the desktop space.
I wouldn't say that's low, but also there was nothing worth covering there yet. So far the presentation even reinforced our beliefs that this seems like their process is mobile-focused as well, as no IPC or clock speed gains were even mentioned. If they had something worthwhile, they would make their promises to prevent people from jumping on Zen 2 in just two days, but it seemed to me like they know that they can't. For now I'd ignore this as the usual 10nm talk, consider this an announcement of additional Coffee Lake 14nm chips and focus on the actual AMD announcement.
