They are sourcing new LCD screens from a new vendor for better reliability. There are also much brighter. Improved the charger powere converter interface and made some minor changes to the RF section. No the range has not increased but it does seem to work alot better. All of these were basically QC issues and they had to bite the bullet and make the changes. The T2 Pro is still in the works but no date for the release. Everything is still compatible with the IRF6.
