Well, one thing they BETTER do is have some DAMN good character models and realistic reactions when they throw! I hated that about brunswick bowling, I need a strike to win, leave a solid 10, and my character just shakes his head!?!?! PLEASE!
Imagine having character models like Visual Concepts does with their basketball game. Heck, come to think of it, since PBA Bowling is on ESPN, mabey they should make the game! I'd want the works! Realistic character models, facial expressions, reactions and everthing. They could even make it where the emotions build up over the course of the game. If a player is getting blown out things are kind of just hum drum because you know whose one the game early on. But have a heated match and have the crowd, announcers, and the bowlers themselves react occordingly all the way to the 10th frame!
As far as equipment goes, I agree with Stormrox, why not have a buch of equipment you can purchase! Figure out how you want it drilled, what you want it to do and how it'll react. There are a lot of games who have this for the realistic gamer in other games, why not have it in a bowling game? Hell, even have a practice session where you can use the CATS system! Now that would be TIGHT!
Also, have the actual bowling lanes that major tournaments are held in and even include the Nation Bowling Center in Las Vegas. (or is it Reno?) I mean there is soooo much you could do with this it's not even funny! I'd just hope that they take their time to do it right. One last thing that would be really cool is if you could have the classic pros avail with the new pros. Ok, I'll stop, but you get my point right?

When you've moved up, moved back, adjusted left and right, cupped, flattened out, have thrown everyting in your arsenal, and the pins still don't cooperate, just say, "Aw to HELL with it!", and throw the ball!
