Turbanator wroteYeah, I agree that it would 99.9% be the same as the G84 but was just putting that out there. Was more curious about the timing.I didn't catch this either, OP didn't let us know of the monthly update like usual 😉.
To answer your questions though, platform will absolutely be the same as G84 (and thus G80/G81), but production dates don't seem to be known yet. There is a 1 year gap between the EV M3 body styles, but that's bc the ZA0 M3 sedan is starting production before the NA1 (i3 Touring) is, so no clue if that timeline will be consistent with the ICE variants.
This news does make me a little more worried for the trimlines of the G51 in the US though. If there's an M3 Touring for sale as well, I'd think BMW would then offer the 330 Touring in the US rather than the M350 to try to upsell the performance-minded customers. I don't have any interest in a 4-pot, nor can I really justify the compromises of the M3 as a daily (harsher suspension, higher initial cost, higher cost of ownership, etc), so I'm really hoping they go for the B58 version instead of the B48 (though I'm not holding my breath at all).
Unless there is something that I really don't like about it, I was already planning to get a G84. I have a 911 4 GTS as my daily/fun can and the M3 is my "more practical" car
but if there is a touring available at the same time as the G84 releases, then I would seriously consider it depending on looks.
