Here's the deal, you know you will be too lazy to sleeve these up and play right after you get them, so what's waiting a few more weeks? Why? Because stores will be so overstocked that these will be selling for $100 for all 5 a little after release. This has been the price cycle for the past two Commander releases and it's going to happen again, just wait, you'll see.
LeeSaltLast two cycles haven't hit this level of EV (Which yes wont sustain) but it will drive the sells and I dont think these will hit lower then the $25 mark unless you have an LGS who doesn't like money.
LeaveMeAloneExcept WotC prints the heck out of these decks. I'm betting they drop, and quickly. If they don't, they certainly aren't increasing. If, for some reason one deck becomes very popular like the 2013 versions, WotC will print even more to lower the price.
