We've just landed a rather large patch in core to bring the Migrate API up-to-date with the sandbox: https://drupal.org/node/2213451 Congratulations and thank you to all involved.
Moving forward, I intend to create an issue in the core queue for each change to the Migrate API. I don't want development in the sandbox to be held up so after discussion on IRC the decision has been made to simply ensure that all changes to code within the migrate folder must have their own issue within the sandbox.
I will then create the relevant issues in the core queue once we've committed the changes to the sandbox.
Any questions, let me know on IRC.
Thanks.
