I'm hearing that timeframe thrown around a lot (1 or 2 years).

It coincides with the next halving, to it's an intuitive fit. It also makes sense to see a long sideways (or slightly downwards or whatever) stretch as it usually happens in bitcoin after a huge runup has corrected. It also makes sense that it would take longer than in the past because the market has grown in number of participants, so it's quite conceivable it behaves more sluggishly.

However my gut says we'll see a substantial rise before 1 year has passed (i.e. in 2015). Not necessarily breaking the ath yet, but substantial. Why? Continual adoption plus the experience of the last halving will have the effect that more players will price in the halving sooner (or at all) than last time, so we might get an ignition before, not after the actual reward halving occurs.
