We have yet to see anything official from Google, not to mention that this is something that will only add to those Google Drive rumors — but it looks like the free storage space for Docs is being increased to 5GB. And for those not as familiar with Docs, that means an increase from 1GB. So far we have seen more than a few reports around the web showing a 5GB limit, however a quick check of my account is still showing a 1GB storage limit. Bottom line here, it appears as if all Docs users are getting this increase in storage, it is just that Google is doing the upgrading in waves.
