It might look that way to you, but the developers are working on LMDE 2 all the time (not a day has passed I didn't seem them working on it in IRC). From last week's blog post:
a matter of word choice as usual. according to the latest official statement LMDE won't get a full system maintenance until jessie becomes stable which is ... only god know when :3
else, did they cancel the latest plan and will release transitional update for LMDE?
please let me know mint's latest future plan about LMDE. meanwhile, I'll continue to suggest user to not use LMDE (use mint main version instead, please) until LMDE 2 got released. here's my reason.
1. LMDE doesn't get security updates. some famous security patch get thru but it's totally insignificant compared with 400++ known security bug missed by LMDE. my latest count more than a month ago is already beyond 400 and the number will keep rising. effectively made LMDE as one of the most vulnerable distro ever. it's insane to suggest a user to install an OS with unresolved bugs and a massive number of security holes.
2. LMDE currently isn't upgradeable to latest jessie. IIRC on the forum discussion that was one of the main reason why the plan to release UP9 on this november got canceled. a 9 months development gap isn't something easy to handle and user will mostly forced to reinstall his system when LMDE 2 comes. there's no point to install current LMDE. it's wiser to wait LMDE 2 got released or use jessie then mintify it instead.
by any means it's not "I hate LMDE" but "I want to protect user".
