the huge header section is the new trend in website design. it used to be putting all the important info "above the fold" (before you have to scroll down). but now it's about putting engaging content above the fold, which entices users to scroll down.
overall i think the new site looks great! things have more space between them and it breathes better. definitely a more modern design.
as for the support and downloads... i too prefer things on one page, and i've designed my site like that - important info that people NEED to read up top, downloads below:
Latest Info | AxeFxTutorials.com dang... i might have to check my links now. bleh!
as with anything though, people will get used to the new site and where to find things. i think the most confusing thing though will be finding Axe-Edit. all the "edits" are now on a tab with their respective products. the old link will still work - good thing - but searching for it, one has to go to Axe-Fx first, then the tab for Edit.
