addame, mummel, it looks like we're all in a similar position.
I'm planning to purchase my first DSLR in the next few weeks and have been trying to determine what to do. Here's my approach:
Waiting to see what Canon does in the next 15 or so days (now through NAB). If they announce the T4i, great! If they don't, I'll likely pick up the 60D or the T3i. They are both great cameras and each will offer an opportunity go through the DSLR learning curve.
My primary use will be video which means I will be swayed by that feature set more than anything else.

Also from a 3/7/12 post:
I haven’t received any specs of the camera, just proof that it exists and it’s coming soon. I expect DIGIC 5, articulating LCD and new movie features. -- http://www.canonrumors.com/2012/03/whats-next-a-general-breakdown/
I can't find something I read about coupons for the T3i expiring today (3/31/12). It would have been in Canon's interest to keep any news of the T4i close to the hip if this is true. My fingers are crossed that info 'leaks' to CR early next week.
Like you, I'm very excited. #fingerscrossed
