The i1pro2 already has a very limited range, the i1pro revE is VERY unlikely to produce good results, even if it was detected. It's limited to around 300nits, vs 1200nits for the i1pro2 (vs 4000nits for the spyders). The i1pro2 is also more sensitive/reliable in the low end, and doesn't need a dark calibration as frequently as the i1pro.
Unless they use the i1pro2 as a spectro to profile another meter (which I don't think is the case), I wonder how the i1pro can do a 33 points gamma+color autocal. I'm not sure how the i1pro2 could achieve that, even with its extended range.
I have an i1pro2 but I don't have an rsx20 model, and the most recent software version that supports our models (V7) doesn't support the i1pro2, so I can't test it.
I haven't heard of anyone having tested the i1pro2 with the JVCs, so I'm very interested to hear some feedback, but I'm not convinced it will provide good results for gamma calibration. It should work great for color though. I might work for 9 point gamma.
[EDIT: I read the software manual for the latest version of the software for the RS4500 and it looks like when using the i1pro2, the meter is facing the screen, which is great as it takes the screen into account (the Spyder 5 is still used facing the PJ). This means that the 1200nits limitation if the i1pro2 isn't an issue, and even the 300nits limitation of the i1pro rev E wouldn't be for most projectors setups, but the low-end limitation of both of these meters still stands. The i1pro2 isn't used to profile the Spyder 5, but is used on its own. I wouldn't trust a gamma calibration with an i1pro below 30% white (I used to have one). I wouldn't trust the gamma calibration of an i1pro2 below 15% white, maybe 10% at best. So the i1pro2 might work with a 9 step gamma calibration, but I doubt a 20 or 33 steps would work. I don't believe an i1pro rev E stands a chance due to its limitation in the low end, even with 9 steps only. These are spectros, they are not meant to calibrate gamma, only to be users as reference meters to profile a colorimeter or to do a gamut calibration / above 30% white calibration]
Personally, if I didn't have an i1pro2 already and planned to use it for JVC Autocal of the new models exclusively, I would wait for some feedback before purchasing one.
Of course beware, the i1pro2 isn't supported with the models on topic in this thread (rsx00) or older models. It's only supported on the rsx20 line and the rs4500/Z1, along with the Spyder5. I don't know if the autocal has been fixed for the new line though, last time I heard it was broken.
