I read an interview on the same site as Polarbit - it says that soon will Reckless Racing 2 in 2012, if anyone should, you can read the full interview! There are changing the language to the English version of the interview - with the top button http://www.orangeiphone.ru/news/940-eksklyuziv-orangeiphoneru-intervyu-s-sozdatelyami-reckless-getaway-i-reckless-racing.html
I would hope the addition of weapons in RR2, if it does indeed happen, would push the game more towards weapons-as-powerup like RC Pro-AM and Mario Kart, and not deathmatch-on-wheels like Death Rally, which is fun in its own right but is now done and over to me. Weapon balance is a tricky business and can make or break a game.
