It probably won't have too much of a sale while in EA.
And, it will probably go up in price when it fully releases.
I would think that, multiple years after release, it'll go down in price again, and then a year after that it will get a good sale. Basically, you could be waiting about 5 years or more just to save roughly $5 off what it is currently sold for. If that's worth it to you that's cool, I usually wait, but this one seemed like a decent deal for the timing.
