Pre-Release Domain Name ( Deindexed)

I've been watching a pre-release domain with valid backlinks and PR, which was recently deindexed from google within 10 days of expiring. My question is, if I place a new website up, will this be reindexed? Or would I need to submit it for reconsideration? Also, after its back in the index, will the site still retain its seo value ( i.e. authority)?

it should be reindexed without any issues, just build your site and add it to Google Webmaster Tools

Same for me

Website was indexed 2 days ago, now deindexed. Lets hope everything goes well

Yep it will. put some content and make sure robots.txt is there
then add to webmaster tool and fetch as google bot.
