From a web development standpoint, HTML5 and CSS3 rock. While they may be in draft [1, 2] (i.e., not official yet), they're both perfectly usable now. Some things aren't supported by older browsers, but that's okay. It's all about progressive enhancement anyway.
But at the end of the day, people don't care if sites are written in XHTML 1.0, HTML4 or HTML5 using CSS 2.1 or CSS3. All they care is that a site works and is readable. A skilled web developer will be able to implement HTML5 and CSS3 now and sites will still be usable by a majority of users.
So is HTML5 and CSS3 "coming soon"? Nah. It's already here.
