I thought for discussion purposes it might be nice to list out the ilvls of the different pve gear in MoP. Something interesting to note, there appears to be an introductory raid which has non-tier gear. Also they imposed a VP cap of 3k, so you can't save it all to upgrade your heroic pieces, unless you get to heroic modes extremely early.
ILVL 463 - 5 man Heroics
ILVL 476 - Raid Finder Mogushun Vaults, a few 5 man heroic epics (only two currently, extremely rare and off the last bosses - a new version of deadman's ring)
ILVL 483 - Raid Finder Heart of Fear and Terrace of Endless Spring, Conquest PVP gear (since pvp stats no longer count towards ilvl)
ILVL 489 - Normal Mogushun Vaults, VP gear, craftable gear
ILVL 497 - Normal Heart of Fear and Terrace of Endless Spring (also all tier gear is from these instances)
ILVL 502 - Heroic Mogushun Vaults
ILVL 509 - Heroic Heart of Fear and Terrace of Endless Spring (All heroic tier gear drops from in these two)
The most important thing to note is that there appears to be some gear gating, also VP gear is a half tier below actual tier gear. So the it appears that the intended progression is do Mogushun Vaults, gear up in 489, then progress onto Heart of Fear. Also note that Terrace of Endless Spring supposedly requires that you complete Heart of Fear first. I think this is a step in the right direction for increasing difficulty and giving most people a sense of progression. When there is only one raid, with all item levels the same, something is lost.
