I agree, but I don't think folks are saying it's going to overtake Dropbox _because_ of the accompanying productivity software so much as the integration of that and the syncing of normal files.
Easier to explain via my own example: I have Dropbox, and I'm also a fairly heavy docs user. Now that's there's Drive, it's a no-brainer to just take all my files out of Dropbox and drop them into Drive so when I'm looking for something like a letter from last year, I only have to search one web site / app and it's got everything from docs to PDF scans. There's no comparable way of going the other direction (moving all my files to Dropbox) without losing a ton of functionality. Word is good, but it's really primitive compared to Doc at this point when it comes to collaborative work and access on my phone, tablet, etc.
It's also worth noting that in the case of Google Docs, Drive isn't really a syncing solution (unless you're using Docs in offline mode) since there's no files to sync. It's just a way to access your docs.
