The only thing they could potentially update is the hard drive size. The Draft-N wireless spec won't change, the interfaces won't change (it's supposed to work wirelessly, so there's no point in adding FireWire or even eSATA), the form factor is fine as it is and the software can be updated at any time. So just the drive size, really. You could just buy the smallest/cheapest and install a new hard drive yourself. Don't know if that voids the warranty, but it's the easiest way right now to get an 'all new and updated' Time Capsule.
