PHP 7 is reaching beta status and lots of testing is going on at the moment. Given that Magento caught up within the last year from "runs only on PHP 5.3" to "fully compatible with PHP 5.6", I would like to know how much they are considering PHP 7 compatibility for Magento 1.x as well as Magento 2.
I found this post by Anna Filina where she found one issue in Magento 1.9.1 (still unchanged in 1.9.2), but given that Magento 1 does not have unit tests, I don't trust that this was the only issue.
So the question is: will PHP 7 compatibility for Magento 1 be ensured? And as Magento 2 probably has already been tested on PHP 7 (Thank automated tests!), are there any known issues?

Magento announced officially on January 20th, 2016, that CE and EE 2.0.1 officially support PHP 7.0.2.
