The only change is that you won't have DLS access unless you buy a First Class Ticket. Helpdesk haven't given technical support for a while on 06, and we'll all still be here on the forums to assist. Or you could use the next five months to save up for TS2010.

I haven't? I'm pretty sure I'm still giving support for 06, until September.
We haven't actually given technical support for 04 or older (apart from assistance with DLS issues with these editions, or some suggestions that may work, such as intro-disable or suggesting they update drivers), as per this announcement from Rob in 2008: http://forums.auran.com/trainz/showthread.php?t=21235
