Yes, there is usually little risk in waiting on most items.
At the same time, we are talking about a four-film Blu-Ray collection for $20. I paid $70 for the same set and still don't regret it. If you don't already have this box set, get it now. It is well worth it.
I can't stress enough just how good Alien and Aliens look on Blu-Ray, or the sheer volume of extra features that this set comes with.
