It will probably be full, but there are a few things.
First, I believe they are moving to the "app store" type of sales. As in, you will be able to get in the windows store and buy any software you need there.
Second.. I heard that most software (as in, photoshop etc.) will go subscription mode. Which will probably need a valid windows 10 copy.
And third - Microsoft has been trying to get their OS on mobile for a while, without much success. Windows 10 might just be able to do that, they have learned from their windows 8 mistakes, I trust. This might mean free(or paid) cloud, shared between all your windows 10 devices, which would be great.
Just off the top of my head. :)
