I think KNH got it pretty much covered. Most of those bands are ones I would have recommended myself, especially since TA and SB are pretty much my cup o'tea.
I'll double-recommend Kaipa, The Flower Kings, The Tangent, Karmakanic, Hasse Froberg & The Musical Companion, and even add Agents Of Mercy and Roine Stolt's solo stuff (especially the blues album Wall Street Voodoo, which features Neal Morse!).
And of course, as others have said, Neal's solo out put is pretty damn good.
And definitely a shout-out for Mars Hollow and Unitopia, two of my favorite recently-new bands to come out in the last few years. MH only has 2 albums, and Unitopia have 3 with a fourth coming out this summer (a covers album, which has been said to be unlike the usual covers album).
I'd also like to throw out Frost* and Kino, as well as Flying Colors (if you haven't heard it yet!).
