It's fairly simple.

"Our product has been released and will be available to buy in the UK on November 25th, France November 27th, Poland November 30th, India December 15th" and so on.

People are getting topics very confused here. The product delay is over. The thing has shipped. Does anybody know anything more now than they did before it shipped? Nope.

As for the other stuff: Nokia announced the product at the end of August. At that point it seems highly likely they were planning an early October release. Instead delays have pushed it to late November. So while you're saying "But other manufacturers just show it to you later in the development cycle" that's because they're able to properly estimate their development cycle, Nokia constantly gets its wrong so it ends up showing off hardware that has months left to run instead of weeks.
