Upgrading to deluxe?
Wait a while and buy the deluxe upgrade with gems when it inevitably gets added to the gem store, like digital deluxe was.
I already bought the HoT normal edition, can i still upgrade to deluxe just by paying the 30 euros?
The answer was given in the presentation of the prepurchase: No

you can skip to 2:20 if you don’t want to watch the entiere presentation.
Correction: you cannot upgrade to ULTIMATE from either, because Ultimate is essentially just $50 of gems for 50% off.
It’s hard to do jumping puzzles with a big, fuzzy butt.
You can, as there have been posts showing the response from the CS Team assisting those that wish to upgrade.
Or, as suggested above, you can upgrade through the Gem Store once that feature becomes available.
Be aware, though, you can only upgrade to the Deluxe Edition; the Ultimate Edition is not available as an upgrade.
Good luck.
