send me the Microsoft link for this batch list and where you fine word never in windows blog for L820?
I doubt that's possible. That's a very old list and was removed months ago.
Prakash's claim that MS promised an early 2016 release is also not true. That information came from an undisclosed source within MS and was reported by M.J. Foley. If Prakash had read the first post in this thread he'd have known.
I'd say March still counts as as "early" 2016 (barely), and although sooner is better than later, MS has not publicly committed to a release schedule, so there is no promise they could break.
MS can legitimately be criticized for not making the original release time-frame that they were aiming for (December). MS can also legitimately be criticized for not providing us with any information. However, practically all the information in this thread about broken promises and alleged release dates is just FUD.
