Sigma Lithium-Ion batteries for SD9/SD10

Sigma today announced a new Lithium-Ion battery and charger kit for the SD9/SD10 digital SLR's. The kit consists of two rechargeable Lithium-Ion CR-V3 batteries (BP-11, 3V, 1160 mAh) and a charger, this kit is expected to retail for around £59.99 in the UK. It's not clear at this stage if any decision has been made to include this with the SD10 digital SLR kit but to me it would be a logical move and would at least bring the SD10 in to line with other digital SLR's from a power supply point of view.
