Magento 2 and Zend Framework 2

Question

Since Magento is planning on using Zend Framework 2, does that mean that all the current extensions that utilize ZF1 are going to break? From what I know about ZF2 and ZF1 is that they are very different in some ways. Especially with namespaces. Wouldn't this hurt them a little? Or, do you think they are anticipating that ZF2 will be a hit?

Answer 1

AFAIK Magento 2 will not use ZF2.
But this is not relevant to your problem.
Since there is no backwords compatibility between Magento 2 and Magento 1 all the extensions that exist for Magento 1 will not work for Magento 2 anyway no matter what ZF version is used.

Answer 2

It is not planned that Magento 2 uses Zend Framework 2 as this GitHub issue proves. There is also no other information regarding this topic in the Magento 2 Wiki.

Answer 3

We view Magento as it's own framework and usage of other code more as libraries to be leveraged. If you look at Magento 2 Dev Beta you'll see ZF1, ZF2, and Symphony libraries being used. Internally we view these libraries in groups that support specific functionality or business objectives and will address their possible upgrade/etc as appropriate in that view.
