###What are the rewards exactly?

First of all, we hope you have a ton of fun playing! Here are the in-game rewards you get to unlock:

 

• 3 Gear items: Handyman Nemesis, Sugar Rush, and Fleet Feet
• In-Game cash
• Learn about the city of Columbia and its factions through story chunks.
• Facebook pack that pledges your allegiance for either the Vox Populi or the Founders

###Are there any additional rewards?

If you pre-order BioShock Infinite at GameStop, you’ll receive the Comstock China Broom Upgrade while pre-ordering at Best Buy will get you the Comstock Bird's Eye Upgrade.

Basically, from what I read, you'll simply have an option to post to your wall either a "I support the Vox Populi" message or a "I support the Founders" message. Additionally, if you fail to complete the puzzles, you may not get to have the Gear items or the in-game cash. You can also opt out of all rewards.

The passage you have quoted is in the "Industrial Revolution Gameplay" section. So, assuming 2K won't change its mind (which is totally possible, but we don't do speculation here) — yes, picking a faction and sticking to it (or not) will change things within Industrial Revolution (such as access to exclusive newspapers); it won't, however, affect [the rewards you get in] Bioshock Infinite itself.

Excluding rewards, will picking sides not affect your playing Bioshock Infinite at all? The thread you quoted doesn't say. We don't do speculation here, so tread carefully.
