According to the Magento newsletter, there will be a Q&A on reddit regarding Magento 2. You will be able to ask any developer related questions there.
Dear Magento Developers,
Now that you’ve had some time to test out Magento 2, we’d like to hear your feedback! We are hosting an Ask me Anything (AmA) focused on the Magento 2 Developer Beta on February 5, 2015 from 8:00 a.m. – 10:00 a.m. PT. It will happen on Magento subreddit.
Ben Marks, Magento community evangelist, will be moderating the session and he will be joined by Magento 2 product, architecture and technical development team members. This is a great chance to engage directly with the people behind Magento 2 and present your input on the Magento 2 beta codebase.
