Congratulations also, I think you be pleased. I was planning to order a 2012 as well, really like the red over silver. However, per their website the red/silver is only available on the standard model, not the Tour
Re: add ons, Maxim's Powersports sells for 20% off, no sales tax. You might try to get a similar deal with your dealer if you want to buy from him/her. I have found the Victory accessories to be generally "very" expensive. In several cases aftermarket stuff is both better and cheaper.
I have the Lloydz cams on my 2011 and it made a very significant difference.
When I had my RoadGlide I found that unless going on a trip I left the top case off. It was great for storage but adversely affected the weight distribution and feel of the bike. Adding weight high up and far back on the bike isn't so good. My buddies with Visions say the same. This, however, could require a different passenger backrest. Victory sells on for maybe $300 (??), aftermarket are less.
I thought the Cee Bailey bag inserts were nicer than the Victory's, jmho.
I plug my Zumo 550 into the existing power plug on the dash, didn't bother to hard wire it.
My perception is that, for many, the new windscreen on the Tour is so tall you may have to look thru it rather than over it, obviously depends on how tall you are. For me this is fine in good weather and really helps buffeting, but if you are in the rain it is difficult, much worse than looking thru a visor. Victory sells a shorter shield, lots of aftermarket ones for less $$ if this is an issue.
After a bit of research I concluded the Utopia rider's backrest is far superior in comfort and less price the the one from Victory.
If you buy within 14 days of a factory demo ride you get a $1000 in free accesories from the Polaris
