MyVegas - how much longer?

Does anyone have any idea how much longer MyVegas will continue? I've noticed the room rewards don't show any availability past March with the exception of special awards specific to certain hotels. I'm also not seeing anymore tickets for "O" showing up.
The Mirage does have one room offer that is showing up into May (mid week for $48). I had emailed myVegas several weeks ago asking when May dates will be available and they replied that they are working on them and will be posted "anytime now". I received a survey last week regarding myVegas offering rewards to WDW, Universal Studios, SeaWorld, etc. so I'm sure they are planning to continue on and expand.
Wow. They were sold out, of course, but just saw a new offer for free play at MGM.
Thank you for the replies. We don't go until September so I'm hoping the rewards will still be available for that time (particularly the room awards). We had a wonderful trip this past September thanks in part to some great MyVegas purchases.

They just opened up dates for the hotels through 9/30/14. Already booked 2 nights at MB and 2 nights at Aria for the end of September!
I thought you had to use the reward within 90 days of getting the reward?
For hotel reservations you just have to book it within 90 days of purchasing the reward.
They are showing award nights through September now maybe even October. They can end the game anytime they want to, just like CET has dome in the past. So I would cash them in instead of hoarding them. The awards seem to keep getting more expensive so you wait to use them you lose much value.
