Woz is an amazing game and is so loaded with stuff. Hobbit is more open with less stuff on the surface, but I'm hoping it will also be amazing in it's own ways.
To me, pinball is basically a "shooting gallery" type of game. Fun shots that when hit give a satisfying result in the form of points, sound, lighting effects and game progression.
I'm thinking JJP did not go through all the effort to put 11 individually controlled drop targets in the game (with stand-up targets behind them) just to use them as they've been used in the past. Cactus Canyon only has 4 individual drop targets (not in banks) and they really add to the gameplay.
Even though the playfield layout looks a little ho-hum, the potential is there with the Hobbit to create a playing experience unlike anything we've seen in the past.
For example, I can envision a mode where one drop target cycles around the playfield or another where an opening between the drop targets cycles instead. You can create a similar effect with insert lights but there is just something special about mechanical movement to me.
That potential combined with the degree of polish JJP put into WOZ, the LCD assets, sound, lighting and animated talking Smaug are what have me anticipating one heck of a shooting gallery.
It's all up to the imagination of the programmers and the time they are given to work on it.
