Bro, if you do not mind about intermediate unit, there are still some available.. furthermore, I believe it is not their official launch. Not all the units are available for booking.
Yesterday, they only made 35 units type 'B' available for booking (located along the first entrance road). This evening, another 36 units of type 'A' available for booking.
If you go tomorrow you should be able to book ahead other people. If not, just wait over the weekend and I believe soon they will launch the remaining units. Price wise I don't think there will be too big gap. Which type are you planning to get anyway?
