We can confirm after some discussions with the clever people at Fuji, that there will be a major firmware upgrade released very shortly. This upgrade will sort out some of the functionality issues you may have been experiencing. In the mean while make sure you updated to the 1.01 firmware anyway. We will keep you informed about this new firmware.
Stock wise, OMG we might have a couple X-100 for stock out of next weeks shipment, so if you are after one best you give us a call.
In regards to getting Raw Convertors that are Fuji X-100 Compatible
We also just received some Hoya HMC UV 49mm filters just perfect for the Fuji X-100
