Old BF2 player here. Bf3 seems promising, but I hope this attempt at becoming a COD-like (retarded solo campaign, retarded tiny maps with full infantry...) will not be too prevalent.
The Battlefield PC series were the only "casual" shooter that had a full range of vehicules, each one of them useful, with it's own handling, weaknesses and strengths. I hope they will not turn this into two swarns of infantry shooting and stabbing each other... I don't know what's the deal with CoD. Maybe they think "Modern Warfare" means "18th century warfare"...
