I guess really, it's going to be a bit like leveling in that game we all know.
At the moment were all playing in the level 35 zone. DF 2.0 will be more like the level 80 zone, nothing that came before really mattered.
The economy will explode beyond what it currently is.
Gold will rain from the sky
Items will be obtainable with general ease, craft mats etc
The things you will need for the new best armour's / weps, ain't even in the game yet.
This will be an extension, beyond what DF 1.0 is currently.
Stockpiling anything now will be semi pointless, as the best items wont require anything we currently have access to.
Just play now, make your clans, grow in strength - skills - atts.
Carve out your terrain, stockpile resource on the side and wait. Just wait and kill, hold onto what you have and see what happens.
Everybody will be on equal footing after 2 weeks of DF2.0 being out, and thats when Banded Wars 2.0 will begin, by twang of swords and a plethora of new catchphrases when you get stomped into the dirt.
If anything, start stockpiling players, they will be the MOST important resource come 2.0
