HTC’s outlook through the end of the year looks promising to them as they plan to rake in at least $3.3 billion after doubling smartphone shipments to 9 million units. For the entirety of the year, they expect to reach 24.5 million units – more than double the amount of units they shipped in 2009.

Android will play a key factor in their success, just as it always has, but let’s not forget that HTC’s banking heavily on Windows Phone 7. They have several phones launching this quarter for carriers around the globe, but it remains to be seen how much momentum Microsoft gets thanks to their generous push.

And yet, HTC still expects Android to gain share rapidly, saying to Reuters:

We believe the overall pie is still big enough to have at least three to four tier-1 players enjoy the growth momentum.

But that growth momentum will take a skid, they expect, as other competitors aren’t sleeping on the Android or Windows Phone 7 train. LG and Samsung are two of the biggest supporters of Microsoft’s extensive mobile re-branding, and they both have their cards in the Android space, as well (with Samsung being more notable than LG in that particular regard.)

Competition is healthy, folks, and there’s no doubt it’s plentiful. 2011 will be a great year for smartphone addicts.
