On March 20 the Rams sent out a letter announcing the live steam for the logo reveal (which happened on March 23).
That same letter said this about the unis: "Later this spring, after years of planning, designing and receiving considerable input from our fans, we will roll out our new uniforms."
Then there is this from Rich Hammond of The Athletic: "... the Rams currently plan to introduce the new logo/colors before the draft, and then the actual uniforms after the draft."
So ... After the draft (currently April 23rd thru 25th) and before the end of spring (which is June 20)?
My opinion: it depends on how long it takes them to scrape that 'LA' logo off their prototype helmets and put the horns back on ...
