More than half of developers believe BlackBerry will be dead in 5 year's time
But Windows Phone to remain relevant
A sweep of 300 studios for the app store's latest developer survey claims interest in Microsoft's OS is growing steadily.
In contrast, confidence in players like BlackBerry, which already enjoys a far stronger base than Microsoft OS, is falling away.
Time for tablets
It's Google's platform that, overall, is beginning to take charge of the development community, however.
As detailed on the GetJar blog, developers believes work on Android both in terms of smartphone output, and titles for tablets will increase over the next six months.
47 percent of studios believe they'll be working on Android tablets in half a year's time, for instance, even though just over 20 percent of them are developing for them now.
"So it seems that developers are really looking at Android tablets as the next possible area of opportunity," adds GetJar CMO Patrick Mork, who will soon be leaving his post to move to Google as marketing director for mobile apps.
"We found that although iOS development remains strong 80 percent currently developing for iPhone and 59 percent developing for iPad - that the Android army is catching on fast.
"Another note of interest as well was the growing interest in Windows Mobile. Mango seems to be tickling developers pink with 24 percent of developers saying theyll develop for OS compared to less then 9 percent today."
Staying off the bottom
Indeed, what will cheer Microsoft is the assessment by 70 percent of developers that Windows Phone will still be a viable platform in five years time, behind Android and iOS on 98 percent each.
That's an important vote of confidence in Microsoft's platform as it looks to distance itself from fellow bit-part player webOS and former giant BlackBerry.
In terms of future planning, GetJar's numbers already brand Windows Phone as more tantalising prospect than both said rivals.
"Blackberry still faces some challenges with less then 15 percent of developers interested in developing for the platform the next six months," details Mork
"Less then 50 percent of developers believe RIM's platform will survive the next 5 years."
Mork claims Symbian is in an even worse position, with less than 7 percent of studios looking to develop on the platform during the next since months.
In all, only 20 percent believe it will still be around in any meaningful sense in the next couple of years.
