Well Josh and David are supposed to be doing a glider shootout so I fully expect at least one and probably two glider designs in the near future (I'm guessing they'd only do a SBK version of the "winner" but wouldn't be surprised to see them post plans for both.)
There's always the fowl flyer for an alternative swappable FPV plane. I keep forgetting that it's a swappable and have it on my build list. (In fact have all the parts on hand so will probably try and start a build on this week...just been too busy to build anything the past few weeks.)
And as others have said they're really all park flyers (the spitfire is more fun with more room and I assume the cruiser is as well....but I had fun with my spitfire at the park this morning.)
As for STOL pretty much every one I've built leaps off the ground in just a few feet (the BW does great vertical takeoffs) and can drop out of the sky in very little space with just a little skill. Though I wouldn't mind something styled more like a traditional bush plane...and suspect we'll see some of those come out of this:

That being said I'm all for more swappables, but they really do have quite a selection already. Since they don't have kits for them yet it's easy to forget the FF, OF and BW...lets see...can I name all 10?
Nutball
FT Flyer
Delta
Bloody Wonder
Fowl Flyer
Old Fogey
Baby Blender (v1 and v2)
FT3D
Cruiser
Spitfire
Yep! Looks like I can
I haven't done a 3D yet since I'm waiting to see what kind of tweaks they make to it before releasing the SBK. And I haven't done a cruiser yet because I only have one higher power pod. (I do have 2 24g motor pods but I'm not sure how well the cruiser would do with those instead of the bigger motors)
I haven't done the FF yet since I keep forgetting about it and keep forgetting that it's a pusher and good for FPV. I've been thinking about shoving my beat up disposable camcorder into the nose of the Old Fogey since it's such a gentle flyer...but I don't think it would do well with that much weight up there. I really should build up a FF I suppose....
