Setting the major mode of a new buffer interactively

Differences between setting major mode keys with a hook versus adding them to the mode mapUse two major-mode-maps in the same bufferChange the default mode used when opening a new bufferNew buffers of the same name don't inherit default major mode?How do I get the current major mode?Make major mode be used by default for new files in directoryWriting a Major ModeSetting the Default Major Mode?use a major mode from the internetRecentf buffer is not interactively

When creating a new buffer via:

1. C-x b


2. 
   NonExistentBufferName RET RET
   

I would like Emacs to prompt me for the major mode this buffer is going to use upon opening.
Moreover, I want Emacs to infer the major mode in some cases based on the buffer's name:

1. C-x b


2. 
   test.org(no such buffer/file so far) RET RET
   => org-mode is used without asking me anything.

Could anybody advice on how I can achieve this? Package or, probably, just pure elisp with its hooks and advice?

P.S.
I'm using ido if it matters.

I know this is not exactly what you're asking, but the Emacs way to solve this problem is to use C-x C-f instead of C-x b (if you don't want to create a file, just don't use C-x C-s in that buffer).

  Thanks, @Stefan, for such a prompt response. Yeah, that seems to be a solution. I was a bit worried about the scenario when I finally decide to save that buffer. If it is already associated with a path and I want to change the final location, it is a problem. But seems like C-x C-w solves this problem.
