they're not putting them back... they're adding converter functions that convert these formats to DBO on loading.
but i wouldn't worry - cause as soon as i can get my grubby hands on the DBO format there will be some exporters being developed for the more used 3D Packages, Milkshape/Maya/3DS Max - i can't code for Lightwave or trueSpace yet, cause i've never figured out howto get a plugin working.
but hopefully for these main packages will be good enough for most users (especially as most seem to use Milkshape or 'not-quite-legal' 3DS Max)
