I'd like to offer a unique concept. How about you put resources on your current bread and butter game vs. using them on future games?! You won't have a player base for the new ones if you can't do something as simple as eliminating error codes. We made you what you are, without us you're nothing!!!
It's called not putting all your eggs in one basket.
At some point everyone needs to not rely on one game to keep the studio going and branch out. Also at some point all development on Destiny will stop and other projects will be needed go support the studio.
For Bungie to have at least one other game in development is no surprise.
