Yeah, others who have been in touch have said the same. As stated, any issues have been isolated (and, from what I can tell, limited to the top riders in the world - even then it's just the forks haven't been lasting as long as the prototype sets) so most forks will be absolutely fine, it's just Trialtech want to 100% ensure rider safety.
Extra info has been added recently:
Update 2:10pm: The offer of a refund or replacement items is open until the end of April 2014, no matter how old your forks are at this date. However, we understand if you wish to continue to use the fork should you have had no problems so far, but we must stress that this would be at your own risk. Once the end of April 2014 has passed, any forks outside of the normal 6 month warranty period will not qualify for the recall scheme.
