On the Test.ical.ly blog there's a new post looking ahead to the next release of PHP, 5.4, and what it could mean for some of the popular tools out there - specifically Symfony and Doctrine.

It shouldn't be long until the first alpha version of PHP 5.4 will be released and with it there will be a lot of new features such as array dereferencing and traits to name but a few. What does that mean to the roadmaps of Doctrine and Symfony?

He mentions the experiments that are proposed on the Doctrine project that could be one of the major driving forces behind Doctrine 3. He points out that, as long as Symfony stays non-PHP 5.4-only, users will still have the choice of Doctrine 2 or 3. There are two issues he points out, though, that could cause problems for both projects - the choices Symfony makes in things like its quickstart guide and the DoctrinBundle vs Doctrine3Bundle situation that could come up.
