To answer the question about wireless lag, it's been tested and proven that the official Xbox 360 wireless controllers and SixAxis/DualShock 3 controllers have no more lag than wired controllers. Wireless technology has greatly improved and not everyone realizes that yet. The Tekken stick is very unlikely to have lag on 360 where it will be using licensed wireless tech. The PS3 version might use a wireless dongle instead of Bluetooth, which could result in a performance hit, but it's impossible to tell until it comes out.
