Time Capsule has been updated by Apple. Time Capsule line of wireless storage hard drives is coming in 2TB which cost $299 and 3TB models $499.
According to ModMyi:
The product description page reflects the increase in capacity, but doesn’t mention the addition of a Thunderbolt connection, or how the devices could possibly interact with iCloud or with new features in Lion like versions. If the devices lack a Thunderbolt I/O it would make sense albeit be unfortunate, as Time Capsules are wireless storage devices. Still it would be nice to have the option to take advantage of Intel and Apples new speedy I/O.
You can expect Time Capsule to be more noticeable in coming months when the users will get use of the devices.
