Will Geotheme still work the same

I have been using GeoTheme for over 2+ years now and love it. We use it on one of our sites http://www.topofny.com and are very happy with it. We understand that you are not selling or supporting GeoTheme any longer but would like to know if we can keep our Geotheme site TopofNy.com without updating to Geodirectory? Will Geotheme still function the same for ever? We had our front page customized and spent a lot of money on it and wouldn’t want to lose it since we just recently made this homepage customization. Will Geotheme stay the same always or will we have issues with it? Also, we have updated WordPress and then read that for Geotheme to work properly, nothing should be updated? We did update WordPress to the newest version and everything still seems to be working properly on our site using Geotheme. Please confirm if we can continue using Geotheme on our site Topofny.com. We will be buying Geodirectory for 3 other new sites we now own but would like to make sure we can still continue using GeoTheme on our http://www.topofny.com site without any issues moving forward. Please confirm and also if we can still update WordPress without issue when it is required to update? Thank you sincerely. We love your work and will be purchasing your add-ons and bundle for $200 soon for our 3 other sites.
