Inline 6s died out because of their length... they are so long that it has an effect on styling (consider the long noses of Supras and S30/S130s of yesteryear), in addition to the huge shift towards front wheel drive. You can't squeeze a long inline 6 into a front wheel drive car, and since economy has become a major concern in the automotive industry, front wheel drive has become more common as it is more efficient.
The goal of the automotive industry is to generally put the biggest displacement engine into the smallest package; V engines do that best. I4s are smaller, so they don't have a notable impact on style, and as a result there's no common reason to make them in a V configuration (they're small enough to begin with, usually).
However, you are wrong about there being no V4s... there several are V4 engines in existence. Not only are they used on motorcycles (due to their small overall size), but Ford used one in their German Taunus, and Saab used one in the Sonett as well. Again, the V configuration is used when space is a concern; in these cases, motorcycles and tiny econoboxes.
In terms of performance, V6 or I6 makes no real difference.
Inline engines are easier to work on due to more space on the sides, hence why you can fit a massive single turbo on a 2JZ or RB26, but if you were to bolt equivalent twins onto a VG30, it'd make as much power as the [nearly equal sized] 2JZ and more power than the [smaller] RB26, all else being equal (intake setups, throttle body sizing, manifold flow, etc - keep in mind, the VG30 does excell in overall flow and there's not much room for improvement).

Reguardless of how many more main bearings the RB26 has, I've never spun a bearing and it's not a common occurence with the VG30 anyway, so it's more of a "just in case" advantage, at that.
I must be missing something...
