Tier 2
I think the crazy Symmetrix gravy train may be coming to an end. Take up of Vmax seems to be slow in some of the shops I have worked in. 3PAR, IBM XIV, and a drabble of Compellent seems to be eating into some of the mid-range/ lower high-range. Tiering within a box can be a false economy, your're still putting "tier 2" on ultra expensive tier 1. If you can bang out 40-50k IOPS on a product that is half the price, then tier 1 needs to provide value propositions that usually aren't there.
