May as well wait, as it will only be a week and a few days (if the rumor is correct). As long as it's for a personal website, the updated iWeb should meet your needs.
If you ever are looking for something more professional, check out RapidWeaver. I use it for my website (non-personal), and love it. I wouldn't go back to iWeb tho. But if iWeb works for you, stick with it, as it's free and way easier to use. I'm sure the next version of iWeb will come with more advanced features, making it a possible choice for business owners.
Agreed. The only browser that could understand my iWeb website was Firefox. Even Safari couldn't display it properly. This was a year ago, though. I've since then ditched iWeb.
