I think they fear that there is no market for it. And they may be even right :-) Nokia and others moved to miniSD/microSD.
I am thinking about hacking miniSDHC card into N770. It should be possible. My idea is to stick/solder miniSD to SD adapter (that comes with each miniSD card) permanently on top of current mmc slot and cut a slot hole for the card in the black plastic on the right side when display is up (i.e. not on the bottom) and let the mmc slot otherwise untouched. One could either insert normal mmcmobile card via original doors or remove it and insert miniSD into the adapter from the right side. Both cannot work at the same time but it is not a problem with 4 or 8 gb miniSD cards. I have not opened my 770 yet but from outside it looks like the adapter should fit in.

That's not a bad idea, a little tricky maybe but certainly not bad 
I take it you've spent some time looking over the schematics, as you say the fact that you couldn't use both the MMCmobile and the miniSD at the same time wouldn't matter if you're looking at using 4-8GB miniSDHC cards; the ability to use MMCmobile would almost become redundant since you're doubling the device's capacity at the very least!
Do you have any idea as to when you'll start dissecting your 770?

Actually I will open my device soon and try empty adapter to see how it will fit but I won't cut/solder anything yet.

Maybe for this plan using microSD to miniSD adapter would be easier. But currently microSD cards with >=4GB capacity are not that common.

So the extra 2GBs would come in handy for extra media to keep me entertained. Then again I suppose I could just buy another 2GB card, but that wouldn't be as much fun, for the time being I think I might attempt to remove the memory card door and use a 4GB Transcend MMCplus.

No?
Anyway, I contacted sales support at Kingston Technology to ask whether they had any plans in the pipeline to introduce higher capacity MMCmobile cards, this morning I received a reply...NO! In fact Kingston's exact words were:
