Pre Purchase diablo 2 resurrected questions

Hi!

Am writing here sense i have’t pre purchase yet and would like to ask some questions before i do.

Can i still use my old Diablo 2 game or will it be merged somehow?
Will all content and features be in the game from day one?
What guarantees do i have that i will receve a finish product?

For me, all this feels similar to Reforged. Don’t get me wrong, i love Diablo specificly, remasters in general are awesome to get that nostalgic feeling i had when i first played the game.

But i don’t want a other reforged, so like i want to know if this is somthing i can look forward to, because i don’t want to get my hopes up to far. That’s why am asking.

Have nice day!

From my understanding , everything you have now stays the same. D2R is like a whole new game with its own servers.
