I haven't been here since last July, but since Scott asked the question, I thought I might add my two cents worth.
I have been using Ninja Forge products for more than three years and became particularly fond of Ninja Explorer. Like most of the Joomla world I have moved to J2.5 for new sites.
As noted in the first post in this thread, it has now been a year since inquiries started about a version of NE for J2.5. Despite John B.'s remarks from SEVEN months ago nothing has materialized. I just checked the Ninja blog pages and they are three months more out of date than John's post here.
I am not writing this to be snarky or mean. There are hundreds, if not thousands, of web folks who have depended on Ninja Forge for excellent quality plug-ins and extensions. I believe all anyone really wants to have is a straight answer.
As far as I am able to determine, you all at NF have "day jobs", families, etc. So do we all. How about just letting us know if there is actual light at the end of the tunnel or just more "Mañana".
Your hopeful customer.
