Will my wife be mad????

Yeah, it usually works out to be fair for everyone in the end.  Let's see: This year you do a stealth upgrade to a new camera body and several new lenses; next year, she upgrades to a guy who is honest with her and doesn't try to BS her about what he does with the family paycheck.  Sounds fair to me.

(And, BTW, if you think a wife is expensive, wait until you start paying for an ex-wife!)
