Lewis Already Thinking Comeback?

Is Lennox Lewis on his way out of retirement for a rematch with Vitali Klitschko? How else to interpret comments such as "The temptation is always there" and "I'd have definitely taken him (Klitschko) out tonight". Lewis-Klitschko II has become a much bigger fight now that it would represent a "comeback" fight for Lewis and with Klitschko having solidified his standing as a top-tier heavyweight with convincing victories over Kirk Johnson and Corrie Sanders. So was the whole "retirement" thing simply choreographed to add value to the rematch? Perhaps ... but there's no disputing it remains the single best match-up available in the sport's glamour division.
