You have to keep in mind that one of the goals of a pinball company is to stay in business. One way to do that is to keep creating fans of their product in a time when all of the younger people have a hand held device which contains an infinite amount of competition. They have to do something that draws new people in and competes against the phone. Once they're drawn in, pinball itself can hold its own against any app on a phone, but they still need something to create that initial draw.
I took my 3 boys (8,11,13) to a pool hall that has 79 pinball machines. When we walked in, where did they immediately go to? The row of Jersey Jack machines. They've grown up with colorful apps, so for them, this was familiar. After the initial draw, they moved around to most other machines, hitting plenty of the new sterns, wpc or system 11 machines. They really didn't have any interest in things older than that.
So, if large screens are what it take to keep the business going, I'm all for it.
