I also don't see how a V-4 behaves differently than an inline-4 in terms of the torque vs top-end power tradeoff. Looking at the torque figure for a Desmosedici RR - it's no different than any current inline-4 1000cc superbike, which are all significantly less than the torque laid down by the 1299.
I like how twins deliver power. That top-end surge on a traditional superbike is mind-warping - fun in the right circumstances but also intimidating. My 1299 is leaps and bounds faster than the S1000RR it replaced, but it doesn't feel as manic; if anything, it feels slower. In other words, I think I feel less acceleration Gs at any given moment, but my overall acceleration rate is faster.
While the idea of owning a street-legal V-4 Ducati, with 230-250hp and a warranty, *sounds* cool (and will undoubtedly literally sound amazing), the experience will unquestionably be different and be more in line with everything else out there. Then the choice ends up being if one prefers an even-firing screamer or an uneven big-bang firing motor. And huge torque numbers will be off the table period.
oh, and HUGE dealbreaker - if Ducati uses a perimeter frame, I won't buy it. I don't care if it's the best handling bike ever made. If I want a perimeter framed bike, I'll go back to BMW.
although...what if Ducati went halfway, using something similar to the BMW F800S frame. Single sided swingarm bolted directly to the crankcase, making the engine a stressed frame member...but then a half-perimeter frame around the motor? There's being faithful to tradition, sacrilege....but what do you call something that's in between? lol
(note: the Panigale breaks one key Ducati tradition - the frame. But it gets a huge pass on this in my book, because Preziosi/MotoGP. It didn't work, but it was one incredibly clever design that makes it a terrible shame that it wasn't successful, and part of my 1299 ownership experience is in homage to Preziosi's out-of-the-box thinking and elegant solutions, doing more with less. It's damned nearly on par with the Britten 1000. Perhaps not coincidentally, both secure the headstock to the frame with minimalist frames and use the motor as a stressed member holding the entire bike together.)
Not so much the torque as it is the firing order that most V4's use which enables them to put power down better than an traditional screamer I4 would. Yamaha decided to give a middle finger to everyone else and elected to use a "crossplane" to get the same effect. Although that method brings up some other packaging and technical issues. Net effect is the ability to use more throttle without losing as much grip as a tradition I4 would, while still maintaining the superior top end performance that more valve area gives.
Kawi was shutting down cylinders during corner exit in WSBK to simulate the effect electronically. It was really noticeable during the broadcasts if you paid attention to it. I haven't been watching much WSBK this year, so haven't noticed if they are still doing it or not. I had thought the electronics rules were simplified so they wouldn't be able to anymore. Doesn't seem to be stopping them though.
ETA: Just realized my response was more towards a track use justification and not how 99 percent of riders on the street will ride. Yeah, can't really beat a 1299 down low whether it's a V or an inline.
