You should find many aspects of the arts similar. That said, there are a few more issues that require clarification before an informed opinion can be given...
You're learning kobudo...which weapon(s)?
Do you practice kata only?
Do you plan to approach karate the same way or do you plan to spar?
Which style (karate) are you interested in?
Is it a traditional style or something like XMA?
Once you've figured it out, let us know.
