Projection lens?

As usual, following Nikon Rumors for new things (although not as closely as I did before getting my D4). They're now speculating that it's likely the 300 f/4 will be updated soon. Reading the comments reminded me; I've heard several people say that they keep a 1.4 teleconverter always on their 300 f/4.

Combined with an earlier post about those teleconverters possibly being discontinued, I wonder if the new 300 f/4 will be introduced along with the new 1.4 converter.

I'd certainly consider buying both, if so (largely depending on price, although there is a question whether I need f/2.8 for gymnastics, too).
