BTS had a limited time to produce CMBO like all game developers. They choose certain AFVs and ommitted others based on what they thought would make the game more complete and balanced. A lot of vehciles didn't make it into the game such as the American M16 halftrack, while other obscure units (the H-39 Hotchkiss) did. CMBB promices to have many more AFVs available than it's predecessor, but rest assured, one or two of your favorits will probably not see the light of day. As far as the 234/4 goes, did it see more eastern or western service? If it fought the russkies in greater numbers, then there is a good chance it will be in CMBB. I myself am more interested in playing with things like the eariler PSW 222 series though.
