I am level 27, 87 hours in, save file 8.8 mb.
I do the quest with the Dragon Alduin.

If there is anybody who has completed the main questline and can confirm whether dragons still spawn or not it will be a big help, I want to know for sure so I can make sure I get all of my dragon souls before I finish the main quest.

THANKS !!!!!

Yes, you will still find many dragons.

Yes, dragons remain in the game upon the main quest completion.

Edit: Ninja'd.

Yes you will find many dragons they will get stronger as you level up from skeletal dragons,dragon,frost dragons,blood dragons,elder dragons,and ancient dragon if you have dawnguard

THANKS GUYS !!!! +1

I have more than 30 unused dragon souls and get 2 or 3 more every night.

Nice to know, because i don't want to left unfinished quests behind...(Nonetheless, i have 8 main quest on my inventory.)
