IIRC, the 400 and 600 were on the list already, so the 500 is new. There are some first images available of the 400, it's (unsurprisingly) a 400/2.8 and it (surprisingly) includes a built-in TC. It's safe to assume it will cost beyond 10k.
The 26mm FX is new to the list (wonder what this might be in the end, given there are 214 and 28mm options already), as are both DX lenses.
That 26mm is indeed odd between the 28mm and 24mm, especially as it is also just specified as compact prime, which the 28mm lens also is. So not a specialty micro.
