Players have been complaining about the Vault capacity in Destiny for quite some time, only allowing for storage of a maximum of 25,000 Glimmer (the game's currency) and 60 items. During a conversation with IGN, Community Manager David Dague stated the following:
"I want so badly for us to add more space to the Vault, because it is a constant, constant piece of feedback. People want to be collectors, and, if we need to expand the Vault in order to let people hold on to their things, then it's something that we're talking about."
Regarding the Glimmer limit, Dague only confirmed that it is "these are things that we're discussing," reassuring that "we're very sensitive to what people want." Still with no update to the Vault capacity, Destiny is also getting it's first expansion, The Dark Bellow, tomorrow and you can check the launch trailer below.
