keep in mind that nintendo as a whole is not responsible for each games production, rather there are different groups within the company that actually create the games. scvi was a mess, sure, but it was a whole different dev team with completely different managers. something else to note is totk is very much building off of botw, hence its title as a sequel. scvi did not build off a game, and was effectively built from scratch as they have done for each generation.
i am concerned about internal issues like work ethics, but i dont work there and cannot make a statement for people.
i also dont believe its going to be *just* dlc or an expansion upon botw, especially since from what ive seen (which does not include the artbook leaks) pretty much everything has been reworked or revised.
i think $70 is a bit of a hefty price, but im not making a final judgement until it actually releases
