Affordable? Okay, probably not so much - on the first view! BUT the M3/M4 is an High-Price and Low-Production car = the best solution to test production processes for new materials before entering mass production ... and this is the main reason why BMW officials say that "...they would surprice us with this car"
I think the weight would be the real surprice with the new M3/M4 ... an (much) lower weight means much better (lower) fuel consumption (real world!) also without engine changes!
Unaffordable? Maybe - on the first view ... but with the splitting into M3 and M4 cars, they could make the M3 easy more affordable by marketing the M4 as more premium and more costly, because it seems like many current M-drivers are "Coupe and nothing else"-Fanboys this strategy could works well ... and so the probably much higher price for the M4 (look at M5 vs. M6) could help to hold the M3 on an affordable price level.
Good info and good point about "warming up" to full aluminum in smaller volumes. I missed the original quote.
To clarify, this makes the rumor/speculation:
F80 = 4 door M3, aluminum chassis not shared with F30
F82 = 2 door M4, aluminum chassis, not shared with F32
