Trust me, I've watched all the video reviews of every Brunswick Bowling game out and coming out and while it will certainly be a better technical implementation, it has 3 major flaws IMO:
1. The presentation is dull as dishwater. Generic, barely customizable characters devoid of personality. Basic Brunswick IRL lanes and few oil patterns.
2. The early game (if it sticks to the other Brunswick games) will suck. Play with crappy basic ball for 8-10 matches, hope to win a tourney against much better equipped AI, then play for 8-10 more matches in hopes to win enough money to buy a ball that can show spin.
3. It's not available at launch AND it is more expensive.
I'm willing to somewhat blind buy HVB (I've played at a friends house with the DS3) because of the above and the fact that for a casual experience, it'll do well enough as a launch game.
If Brunswick Pro comes out and has remedied some/all of the above, I'm certainly willing to buy into it as well.
Update: I just checked Amazon and it seems they have pulled in the availability to 09/19. One problem down, three to go.
