This is purely speculation on my part but given Sprint's track records and their love of any and all things Curve and Bold, there's a better than average chance the Sedona aka the 'new' Curve -facepalm 3.0-, the Montana aka the Bold touch and the Malibu aka the Curve touch released sometime this year. Personally, the Montana doesn't look like a full touch screen phone. In the pics on CB, it looks like only the top portion is touch screen which IMO makes it basically useless to anyone who has hands that are bigger than a 3 year olds.
The Sedona is basically the exact same phone as the 3G Curve, but with a few minor tweaks.
The Montana doesn't look touch screen to me at all. Perhaps they're calling it a Bold touch because of the trackpad?
The Malibu would be a great phone for Sprint to fawn all over. It's a Curve which is their flagship line but it's also a full touch screen phone. If Sprint got this one and not the Monaco, I'd probably give this one a try.
The speculation part comes in here: If I had to guess, I'd say look for the Sedona and the Montana by the end of June. I'm doubtful that Sprint will ever see the Monaco which is the alleged Storm3. The Malibu will probably be their fall release phone. They're not gonna do anything as far as BB goes after they make their big David Blaine announcement next week. I'm sure the hype of that announcement will cloud over everything as far as BB goes because I have a feeling it'll be a 3D droid and these days, it's all about the droid. (sarcasm)
Sprint's big announcement is Monday. I'm sure they'll unveil their 3D droid and that's about it. I wouldn't be surprised of after the conference if we get some specific release dates on some new phones. We'll see.
I hate the Style, too.
