Yes you can get 2003 type Wordart in 2010 and 2007.
Open an existing 2003 DOC file. Word will open in 2003 Compatibility Mode, "dumbing down" all functionality to 2003 standard, including Wordart. You will be able to create any 2003 formatted Wordart you want. Then Copy the Wordart object, and paste it into
your 2010 formatted file. Tada
NOTE: the initial display of "Available" wordart styles on the Insert tab of the Ribbon frankly SUCKS. It is very limited, mostly "pretty colors". So pick any one of the sucky styles you don't really like. It doesn't matter, just get a
WordArt object inserted. When you click on the object, the "Drawing Tools Format" contextual tab is displayed. Click on it.
If you want a curvy shape, in the Drawing Tools Format contextual tab, WordArt Styles group, Text Effects drop down (the "fuzzy blue A icon", same as on Home tab), hover over bottom option "Transform". You now have a whole bunch of curvy path options.
While you are there, take a look at all of the other buttons on that tab. Lots of fine control
There are lots more formatting options that you have to spelunk for (def: explore deep dark nasty hidden caves) them. For example, if you right click on the border of the Wordart Box you get a "Format Shape" dialog box with 14 options, that each have a bunch
of options.
Same applies for 2007 specific features.
