Quite true. To put just a bit finer point on this, what is updated regularly is software; it becomes firmware when it is written to a device such as an eprom. While an upgrade to firmware can be (and usually is) re-writing the software to the device (this also requires separate hw/sw on the host to perform the update), it can also mean a change to the firmware device and even to the PCB. In this particular case, it is certainly possible that the firmware changes are not in isolation, i.e., some changes may be inter-dependent with changes in hardware. Whatever, we don't know what this firmware upgrade entails. (Whether software updates make sense in the future or not, is a technical question for later.) Also, IMO good to keep in mind that SM was addressing broader questions and his references to specific improvements was in advance of the official announcement. A fair guess is that VXL would have preferred to hold this information until then. The several improvements SM cited were not intended to be a fully-explained and complete list. Since by definition further speculation will be inaccurate, IMHO it's best to wait the couple weeks to hear the full story.
