The (possibly final?) word through the grapevine is that August 7th 2006 has been selected as the first day of school. At least, that's the case for the (upcoming) second-years... and I'd assume you'll be in the same boat. Orientation would be the previous week.
On the curriculum issue, I don't get the feeling anyone at TUCOM believes reform is a pressing need. TUCOM students score above average on COMLEX, and no one believe the current system is "broken" by any stretch of the imagination. For that reason alone, they're going to take their time considering the new reformed curriculum. It has to be a consensus that it will represent a dramatic improvement before they'll risk replacing a perfectly functional system.
The current TUCOM curriculum is discussed in detail on the new website, in case you haven't seen this yet:
