my issue isn't that they're taking this long to release the NX20. my issue is that they were going to release two times, yet continued to push it back.
maybe the rumor sites were wrong, but I don't think they were because I have never had a rumor site get it wrong before with samsung's release dates until the NX20. but first the NX20 was supposed to be announced with the NX200 (by which they already had over a year to make the NX20 because the NX11 was basically the same camera), then it was supposed to be announced at CES, then at Prague, but now it's indefinitely prolonged until may.
the same thing happened with their lenses- when they first showed off the lenses behind display cases wayyy back in 2010, they said they were going to be available for sale by the summer, but a lot of the lenses like the macro, 18-200, etc. didn't come until the end of last year! and mind you this was from samsung's display itself, not a rumor site.
I don't mind waiting. But I do mind a company making promises then perpetually delaying things. it makes them look unreliable, unprofessional, and most importantly either undedicated and or disorganized.
GIve us all a break! The dates about the NX20 as you said are from rumour sites, not from Samsung. The dates about the lenses were from a meeting or something, not published on their website. So all these are the same: Internal dates. Internal dates get shifted because of problems or competition or wanting to make changes or whatever.
Your comment about Samsung looking 'unreliable, unprofessional, and most importantly either undedicated and or disorganized' is simply inane.
Have you ever developed anything? Have you ever made something? If so you will have found that you often need more time to make something than you anticipated...
Edit: Even if some dates for lenses were on their website, my arguments hold. Delays happen, this is life. Disagreeing with that is just stupid.
