View differences/Retro tables in Android Zen Pinball World?

I just downloaded Zen Pinball World for my Android tablet and love it, really appreciate the ability to try the tables after watching video. Two questions:

1) I don't see a lot of difference between the different views on each table. It seems like just minor angle/zoom tweaks. Am I missing something or is there a guide that better explains each one?

2) Are there any plans to release any original retro tables from the 1960s-1980s? I know those tables aren't as "busy", but would certainly purchase a "retro pack" in a heartbeat.

Thanks, great game!
