Actually, you don't want the search engines (or anyone else) to see the domain at all until it is 100% ready. Keep the domain parked, and if you already have it moved, block the search engines completely via your robots.txt file. People who see a 'coming soon' page are apt to just never visit that link again. Coming soon is kind of like those old 'under construction' icons - not something you ever want a customer to see.
