Actually, AD would be of no use, since it doesn’t do Motion files, never has. And just on a side note, Wes Plate is (if I’m not mistaken) not with Adobe anymore and is ironically an adamant FCP X editor. Go figure. 😀
If you want the files to remain editable within your NLE (to any degree you wish and exponentially more than in conjunction with 7), FCP X is your only way. Otherwise, yes, you can (only) render them out as clips and use those in whatever other NLE you choose.
