I assume its going to be quite awhile. We have already had two LE Coops and they have not even begun to ship out. We also have multiple items that have not had a coop this year (Aether II's, Smart Strings, Wireless, etc). There will be more as the year goes on and hopefully you can get what you want out of those coops.
as far as a timeline, I doubt anyone knows but RJ and even then I am sure that the LE coop is not at the top of his list at the moment
