Whats the latest on having PHP 5.3.X instead of EOL 5.2.17 as the default PHP install

According to this page http://php.net/eol.php PHP 5.2 has had end of life (eol) on January 6, 2011, at time of posting over 2 years ago.

My question, when will PHP 5.3.X be available as default on InterWorx Control Panel?

IIRC, the iworx guys provided updated packages for centos5, but you have to add a repo. Centos5 (IIRC) offers the php53 packages as well. Centos6 provides php 5.3.3 currently.
