The yaks have the old modeling, and have not been updated to the newer 3d modeling as yet. I am sure they are on the list...like all of the other planes that still have the older modeling on them are... to be brought up to date.
I wish people would understand that HTC has a small number of people working for them and it takes time for these things to get down. This is NOT "Blizzard" where they have 100's of artists and animators to work on updates.
This is very true, both about updating the old models and adding new models. Things need to be considered in a Return On Investment factor, so when one presents a long list of rare, large aircraft that you want added, well, the ROI on them is low compared to something like the A-26 or He111.
The list of units needing to be updated has gotten tantalizingly short:
