The fact of the matter is

I am not a computer genius but I have a question.

They announced their new engine using directx 11 technology last week or so (well there was a thread reporting it last week) and people said that it was most likely be used for their new MMO, which very well could be, and that moving FFXIV would be practically impossible.

My question is why? If their new engine uses the same programming structure, wouldn't it be possible to port it in this new optimized (hopefully) engine?

It depends on any number of things which could in turn depend on any number of other things. SE may have designed it to specifically cater to different purposes than Crystal Tools. On the other hand, they could have designed it with the intent of it being compatible for Crystal Tools upgrades and this is part of the "server fixes" they are referring to. Such matters are also probably company secrets until further notice.

We have no idea really and we currently have no way of knowing for sure unless SE makes some form of press release on the subject. Anyone who tells you otherwise is simply playing the guesswork.
