Yes, concerning stores World of Goo 2 will be Epic exclusive for a while most likely because Epic was a major investor while developing the game.
On the other hand 2DBoy gets 100% of all Epic Store profit during a limited period.
If you are not happy about that you can get it DRM free from the website or wait for the inevitable Steam launch.
Hope this helps :)
It's surprising this and GOG is always such an unpopular option. Most of these stores really dig their claws into the game and force you to launch it through their own shells with all kinds of nagging and network traffic.
I've become convinced most consumers really just aren't capable of "shopping" for software.
I pick that one.

Only pity is it's not available for mobile - the first game was perfect on an iPad with touch as the input method.
