The biggest gap in the games history was 16 months and that was the only time it was ever more than 12 months.
EQ2 has released 8 expansions in 7 years. Even if you throw out AoD since most of the content isnt in game yet (stupid WoW model of expansions) its still 7 expansions in 7 years. I could also compare it to the year where Kingdom of Sky and Echoes of Faydwer were released 10 months apart .
But I was merely looking at the number of new content thats been added to the game in 14 months (since Rift's launch), and the list is quite large. Doesnt matter what expansion it belongs too, its NEW content.
You say get back to you in July/august? Even if Trion releases another patch the size of EI they will be behind still, and august is around when EQ2's Qeynos revamp will come out and who knows what else will be added with that.
