So if I pre-order a CE edition now and don't take advantage of the Beta and everything, will I still be able to get the mount and equips upon launch day? And is there an expiration date on how long you're able to have your CE without using it? Like.... Say game day hits and I don't even touch the thing for like a week or two. Then I get around to it, will my stuff still be there?

Yes, you will still get the items. EME hasn't stated exactly how you obtain the items, so it's hard to say, but I highly doubt they'd do so in a manner that they would expire.

Regardless, with a preorder, you get 30 days of gametime, that will start on launch day (May1st). I don't imagine they will let you delay that.

There's no expiration date on using any account, much less a CE. While it's true we don't know how the in-game items will get to us, it's likely to be the in-game mail. In which case, the in-game mail could expire after 30 days (not sure obviously). However, those usually aren't sent until you create a character.

So yes, you can preorder right now, never even download the game, still start up on May 1st with your in-game perks. The version you paid for isn't going to change just because you don't play the Betas. ;)
