Expansys has now published expected release dates for three anticipated handset sequels, the Samsung Galaxy S 2 (which it misidentifies as the i9100), HTC Desire 2, and HTC Wildfire 2 (codename: Marvel), after pushing its Desire HD2 page live earlier today. We also learn that that the Galaxy S 2 (actually known as i9200) is coming in 16GB and 32GB capacities, and that the Desire 2 will be asking 440 pounds ($707) for an unlocked version in black. The Sony Ericsson Neo, a.k.a. Halon, makes an appearance as well, although no other details are revealed. Posted release dates are as follows:

HTC Desire 2: May 2nd

HTC Wildfire 2: May 23rd

Samsung Galaxy S 2: June 13th (16GB only)

Expect more details at MWC, but with leaks coming at this rate, we may have all we need to know by the time the keynotes start.
