Guild Wars 2

At the HoT FAQ page https://help.guildwars2.com/entries/94582027-Heart-of-Thorns-Pre-Purchase-FAQ it says:

“If I purchase the Standard or Deluxe editions of Heart of Thorns will I be able to upgrade to Deluxe or Ultimate later?

You will be able to upgrade to Deluxe in the gem store, but the only way to receive the Ultimate edition is to buy it from buy.guildwars2.com or in-game."

Does that mean that I can (as a veteran player) after HoT release just buy the Digital Deluxe Upgrade for 2.000 gems at the gemstore and get the same full access to HoT? (Is that then the same game version for which new players have to pay 75$ right now if they want both games?)

And is HoT for free if I already bought the current Digital Deluxe Upgrade earlier? Or if I buy it now? Or do I have to wait until HoT release to buy only the HoT digital upgrade? (without the core game for a reasonable price)

This means that if you buy HoT standard for 50$ or 45€ you can later upgrade it into HoT Deluxe. The current Digital Deluxe upgrade is unrelated.

They are not going to put HoT up for grabs in the gem store (for gems at least) for quite a while most likely.

If they did this, gem prices would spike to 50 gold for a single gem over night…
