Last I heard, it was due out some time this year, but no actual date. The pump coordinator at my hospital also said that they had an internal approval process that needed to be completed by the hospital before the new pump would be available to patients. That was in December. At the time (partly because my pump is self-funded) I didn't want to wait so I finally get an Animas Vibe tomorrow. There should be an Animas rep there, so will ask.
As Tim wrote, you can use the G5 with just the transmitter, sensor, and an iPhone. Not sure if it's still on, but I believe Dexcom were doing an offer of 1 transmitter and 1 sensor for £150.
