I've been of the opinion for a while now that the biggest problem with rituals is that they're not part of the power system. I really hope they're re-written as pseudo-utility powers.
Spit balling, I'd make the casting time for most as Short Rest (kind of like the pre-release Artificer powers). Some longer ones might be an hour, or as part of an extended rest. Most durations would be in the immediate to "end of next encounter" range, with some until "end of next extended rest". Ritual Caster would give one free ritual per day. Additional rituals could be paid for a number of ways - Residuum, Healing Surges, Burn a Daily Power... there's room for playing around here.
A very rough possible example:
[sblock]
Tenser's Floating Disk
Arcana Utility 1
Ritual * Arcane, Creation, Force
Short Rest * Ranged 5
Effect: You create yadda yadda yadda. The disk lasts until the end of your next extended rest or until banished by the caster (as a free action).
Component: 10gp Residuum.

Except nobody would take this as a utility power when Shield is available at the same level and has HUGE combat utility. The WHOLE idea was to make it so that the players don't have to trade off combat utility for OOC utility to such a high degree.
I mean there were TONS of these kinds of spells in AD&D. Nobody ever bothered to memorize them. Another good solid combat useful spell was pretty close to always a winner over something that you might pull out once a level. The only time any of them ever saw use back in those days was if you were a fairly high level caster and level 1 or 2 attack powers were no longer much use. By level 11 a magic user might well have wands and such for ordinary use attack spamming and high level spells for the big guns situations. THEN you'd see some low level utility type spells thrown in for that one oddball situation. Otherwise forget it, I sure wasn't dropping my one or two shots a day of Charm Person to get Tenser's Floating Disc, no way. I might use it as a 'town spell' at best.
Now, a utility power that let you invoke any one of several rituals as if they were powers? That might work. Like I said above though, the exact list of which ones could be applied that way would have to be pretty carefully enumerated. It still forces the player to choose between combat and OOC utility to some extent, but if the utility is high enough that it makes a crucial difference to the party on a regular basis then at least people might contemplate using it.
