I deal day in and out with a supermarket chain and the guys there keep me up to date with MLS sponsors and such (fondly recall the grocery guy hurrying my way one day with a pack of Soft-n-Gentle toilet paper because the MLS logo is now on it), so if/when I see some MLS recognition on a box of Tide, I'll let everyone know.
Yeah - I don't think they annonuced Tide. I am surprised they have been able to keep this new Official spsonsor under wraps. Not even any rumors.
Looks like Tide has been involved with the USSF for a while... http://usyouthsoccer.org/competitions/tide/main.html
