T2i owners aren't ready to jump ship, so I highly doubt Canon will be receiving as much Pre-Orders as the Canon 60D. But for those who are just starting out with no DSLR camera whatsoever it's still one step up from a T2i in many ways. If you're not ready for 60D prices, the T3i is the camera to get. Manual audio levels, new full HD Zoom Crop feature, Swivel LCD, Wireless Flash trigger are all good reasons for a first camera. Although the GH2 seems to be catching some fair marketshare with an almost cult following. I need to dive into mine more.. But if you're looking to start with Canon, the T3i pre-orders are open.

BTW, it looks like all product information for the BG-E8 Battery grips are being updated. The BG-E8 battery grip was originally designed for the Canon T2i and now they are throwing the stamps of T3 and T3i to the supported camera list. This would be a first for a new Canon DSLR to use an already designed Battery Grip, so it sounds like an easier transition upwards for T2i owners who already have these accessories.

[Update] As someone pointed out, looks like the Canon 60D is currently on sale right now. If you're not looking to wait on pre-orders, check out the 60D sale prices.
