Pre-Order download?

Just did my pre-order today and went with digital download option not physical copy, was wondering does anyone know if the phase 4 client will be the one we continue to use or will there be a mad rush to DL on the first day of early access?

I've seen other people talking about the confirmation email that got includes a pre-order bonus package and has the serial code in the email, but mine has no serial code just an order number and says nothing about pre-order bonus package, did I miss the boat for early access and bonus for pre-ordering?

Also it says there is only a 30 day window to download and to keep a copy as back up on an external hard drive because your download button will not be there anymore. I found that a little odd, don't most games just let us re-download as long as we know our serial # and account details? 

Thanks. I didn't get a serial code tho and my email didn't mention the pre order bonus, but other people's emails did, maybe it is too late. I did see something about limited offer, will see if I can find it.

Here: http://na.finalfantasyxiv.com/product/  down at the bottom of the page it says:

Also, please be aware that the number of early access codes will be limited and distribution will cease when the limit has been reached. 

* The pre-order bonus code distribution timing and method may vary depending on the retailer.

I preordered from Amazon.com today and shortly thereafter received an email with a code. They said to go to this URL to enter the code:

http://preorder.na.finalfantasyxiv.com/us

However, if you go there (today) you'll see that Squenix is not prepared to accept codes. But you can enter in your email so they can notify you when they *are* ready.

I wouldn't worry too much about the early access codes being limited... that sounds a lot like marketing-speak to me. I remember when Guild Wars 2 (I think it was but maybe it was Star Wars) had early access that was "limited" and after a bunch of wailing by disaffected gamers, everyone who preordered got in early. 

World of Warcraft - MOP had the same thing. 'limited' early access but everyone who signed up got it
