I guess there will be an update which will add support for PSoC 6 into PSoC Creator. It is not publicly available yet, but I have already seen a few screenshots.
Thank you for your query. PSoC Creator 4.1 is a minimum prerequisite and is recommended for installation to prepare for PSoC 6 software release that is coming up shortly. The version of PSoC Creator 4.1 currently on Cypress website does not support PSoC 6 devices.
Please see this thread for more information.
