I am forwarding this request to the responsible sector.
Just have in mind that PRO and X are quite similar at this point. The big advantage of PRO is the header and footer builder which you are not obliged to use if you find too overwhelming to start it.
On Pro > Theme Options > Header / Footer you can choose to use Classic Header and Footer which will make your PRO theme pretty much like X.
X Does offer demo content which Pro does not, although we have just implemented on the last release the design cloud on Pro > Templates > Design cloud which offers a a good number of page and elements presets.
If you change your mind let us know, anyway your request has already been forwarded.
