Now a good time to buy a sony?

I'm starting my system and I really like that I will save a few hundred per lens to not have to get in lens stabilization. I also really like the 7fps on the 550 and i've tried out the menus and i really like the way it feels (minus the cheepo plastic on top). However, I keep hearing "video soon" and "sony leaving/not leaving". So, end question is, is now a good time to buy or will i regret it? wait til photokina? a whole different company? (probably the wrong question to ask on the sony forum, but may as well)
