I volunteered for the JDRF at an event last week and situated our table by the Medtronic table and the reps were hinting that something would be coming out “very soon” that will be interesting. They weren’t allowed to say anything about dates but indicated it will be a 630, rather than a 640. I googled it but came up with zippo so I dunno what that’s going to mean.

The 6 stands for sixth generation pump, so the actual pump will be like the 640g. However, I think the 30 stands for the Enlite iteration model, so a 630g would probably use the same sensor as the 530g, not the second generation sensor used on the 640g. I think the 670g will use the the third generation Enlite , the one with the letter G on it.
Hmmm, interesting. I thought these were the 2nd generation Enlites that we’re getting now? I had started them in 2013, after dithering a bit and noticed a pretty perceptible, if slight, drop in my A1C around that time and figured we had the improved sensors already but was never sure. I don’t recall if the people mentioned the letter or not, I usually drop them in discussions of Medtronic products but if they have meanings, I will have to pay closer attention! The one sales rep said several times that it would be “REALLY exciting” which made me think perhaps it’s something new. I am very leery of AP types of gizmos unless I get to pick the targets…
I’m not sure, but I think the software for the Enlite on the 640g is second generation, maybe the actual sensor is the same??
My guess would be that the difference would be in the CGM transmitter used with the pump, not the sensor. The second generation Enlite … which I have always assumed is what Medtronic calls an “Enhanced Enlite” … is apparently currently being used outside the US with both the 530G (and presumably earlier) and the 640G.
The incompatible difference in CGM tech between the 530G & earlier pumps versus the 640G is the CGM transmitter. The former uses the MiniLink transmitter which I think has not been changed since it was introduced with the Sof-Sensor (aka Harpoon) sensors. The 640G uses what Medtronic calls the Guardian Link 2 transmitter.
The MiniLink uses a radio frequency around 900 MHz, the GL2 talks in the 2.4 GHz band. This is why a pump which works with one transmitter won’t work with another. By contrast the “Enhanced Enlite” sensors can work with either transmitter.

Thanks for sharing those details @irrational_John! I figured there was something like that but, from my consumeristic perspective, it’s more interestin than exciting. Perhaps they are working on leapfrogging to the 670 which I think Medtronic have hinted might be their AP? I’d find that interesting too, until we’d get more details. It could be very exciting…

I new it!!! i just new it!!! 
! just upgraded to the 530G about 2 weeks ago and the newer pump is coming real soon. Wonder if MM will let me swap out without charge?
There is a Facebook group for the new 600 series. I keep hearing Revel users will be able to use this pump (supposedly the last new pump was really only meant to be sold to CGMS users). I have heard April, based on FDA approval. I could’nt wait for that kind of unknown event, so I bought a TSlim this week. The pathway program will be there for people who need to upgrade, but you gotta be able to deal with that Revel dark colorless screen. Service wise, I liked Medtronic but just couldnt wait it out and really have trouble reading my Revel pump.
I haven’t seen anything much about the 670 yet, so I’m not sure how it will pan out.
This rumor of a 630G which is sorta, kinda a 640G but not really is disappointing to me. It sounds like a setback or possibly a fallback plan for Medtronic if they aren’t able to secure FDA approval for their 640G system in the U.S.
But who knows. Wait and see as always, I guess.
