Yes, the movies stay in your Server as long as you want them there. It is true that Warner is currently the only major studio participating, but K is diligently working on bringing other's onboard. We'll see where this goes, but up to now the store is seeing a lot of traffic and is doing very well. To be clear, these are movies that become available in the store on the same day they are released on DVD/BR. This is NOT the same product that Prima Cinema is selling.
