At this time JA still does not know whether there will be a big push to go and re-visit older templates and add new features to them. JA still have a number of components to update and test and those are the priority at the moment. JA Voice, and JA Comment are 2 examples of big components that are actively being worked on.
However, it is my understanding that our JA Devs have given the “thumbs up” to agreeing to update a number of our older J1.5 Templates – though there is neither a list nor timeframe we can provide at this particular time as to when this will occur. In the meantime, there ARE methods to update the Joomla version manually – from J1.5 to J1.7/J2.5 – instructions for which are available within our Member Community Forum Sections.
At this time, we do not offer customization services through JoomlArt. Should you still feel the need for some professional level assistance, another possible resource for you might be one of the freelance boards –> joomlancers.com, scriptlance.com, or freelancer.com – for example.
