Great news about the Abrams -- so it's just coming with an engine? Hardly seems like an interior to me.
Tamiya is doing the C2 after all? Well, of cource, Trumpeter is now doing a Telic upgrade for its C2, and the upgrade has also corrected many of the kit's wheel deficiencies -- ironic, as you can hardly see the wheels on a Telic C2 in the first place.
If I wanted to do a C2 badly, I would bite the bullet and do the Accurate one. Those are the kits the Vickers and MoD guys have on their desks. Though Tamiy will no doubt give the expensive resin kit from AA a run for its money. Thank you, Tamiya-san!
