Today we can find several signs that Google Drive is arriving in the next weeks. I'v found some hints about Google Drive on docs.google.com in a javascript file:

cg="My Google Drive"
lma="Remove from My Google Drive"
qma="Restore to My Google Drive"
lba=" items haved been removed from your Google Drive."
Uba='" has been added to your Google Drive.'
gha="Add to My Google Drive"

Last week some on Hacker News pointed to a Issue from the Chromium Project:

Unified Diff: net/base/transport_security_state_unittest.cc

EXPECT_TRUE(state->IsEnabledForHost(&domain_state, "docs.google.com", true));  EXPECT_TRUE(state->IsEnabledForHost(&domain_state, "sites.google.com", true));+ EXPECT_TRUE(state->IsEnabledForHost(&domain_state, "drive.google.com", true));  EXPECT_TRUE(state->IsEnabledForHost(&domain_state, "spreadsheets.google.com", true));

Google Storage for Developers is already in Labs-state and looks like a Drive for Developers and has quiet interesting feratures.

Fast, scalable, highly available object store

• All data replicated to multiple data centers
• Read-your-writes data consistency
• Objects can be terabytes in size, with resumable uploads and downloads, and range-GET support
• Domain-scoped bucket namespace

Easy, flexible, authentication and sharing

• OAuth 2.0 Authentication
• Authenticated downloads from a web browser
• Individual-, project-, and group-level access controls

But I think Google Drive will be integrated into the existing Google Docs and we will see some desktop applications to synchronize local disks with Google.
