EV3 is not allowed for 2014-2015 FTC season. So we could in theory use version 3.x. We do not have any version of RobotC right now. Do we know that RobotC version 4.x is allowed for 2014-2015? If it is not allowed, does the purchase of Version 4.x allow us to also run version 3.x? Any guidance on what to version to buy? We would like to be a 6 seat - perpetual version.

Thanks.

As of the 2013-2014 manual, this is the official ruling on NXT firmware:
Note the 3.0 or later.

I would like to assume this would not change, but you can't be positive until next season. I would also check the FTC forums (hosted by First I believe). Also, I do not believe a 4.x license allows you to download 3.x, for a 3.x license doesn't allow me to get 2.x. Also keep in mind that 4.x is still in beta, are you sure you want to compete with that? Best of luck to you guys!

I also sent in a question to RobotC customer service. I'll post their answer here:

The FIRST Tech Challenge competition will allow both ROBOTC 3.X and ROBOTC 4.X to be used next season. It's up to the team which version they'd like to use.

Robomatter/ROBOTC only have ROBOTC 4.X licenses available as that is the current product version - you can, however, use a 4.X license to activate your ROBOTC 3.X installation -which allows you to use the older software for competition, but continue to use the newer software if you have EV3 robots.
