Well, I thought it would be tricky - that's why I made the rough estimate of up to half the list price of a new unit as the cost for the upgrade. What I wondered was if really any parts in the G98 (apart from buttons, PS and feet) would be powerful enough for handling of the higher data throughput needed for the new formats.
