I think increasing compatibility with CSS should be an important goal 
and improvements in native MathML support could help to do that. For 
example, I'd like to see addressed the problem with <mstyle> that was 
already mentioned on this list in the past (BTW, Gecko will drop support 
for most of the unused attributes in the future). Also, the line 
breaking could be made more explicit about how to behave with respect to 
the CSS linebreaking. At the moment, there is not any MathML 
implementation that can handle the basic test case of linebreaking of 
math equations inside a HTML table.

This is related to better CSS compatibility but I'm not sure what you 
have in mind here. Browsers have now converged towards the WOFF standard 
and (math) Web fonts can just be used normally in native MathML 
implementations. One of the current issue is that legacy fonts like 
STIXGeneral are split into many files and one has to explicitly list all 
of them in the CSS stylesheet, which is not very convenient for the Web 
authors. However, with Microsoft's Open Type MATH table that became the 
de facto standard and was submitted by Murray in January for 
standardization, we have a clean way to specify the desired math font 
and all its properties using a single file. So that's now more an 
implementation issue and that's what I'm working on for Gecko/WebKit 
MathML support. Font selection would then become as simple as this:

@font-face {
   font-family: LatinModernMathWOFF;
   src: local("Latin Modern Math"), url('latinmodern-math.woff');
}

math {
   font-family: LatinModernMathWOFF;
}
