Windows Phone 8 users should rejoice as evidently the newly updated WhatsApp and Twitter apps are just the beginning. Microsoft’s Joe Belfiore took to Twitter to react to the mostly positive news by teasing  he has a “few more apps on my #WP8 phone that aren’t in the Store”.

Microsoft in the past has had headline grabbing “app pushes” where a near steady cadre of awaited apps were launched on Windows Phone. The last time this happened was soon after Windows Phone 7.5 was launched with nearly 50 high profile apps being released over a span of weeks.

While we’re certainly not anticipating that many apps this time (Microsoft did just hit 130K apps) there are a few big titles that we’re still missing...

Within the last week, WhatsApp was updated no less than three times and Twitter was re-launched with a 2.0 update. Nokia was working closely with WhatsApp to improve the somewhat troubled messenger, which has suffered from stability issues in the past and we’re unsure about who was involved with the Twitter refresh.

So what are those Windows Phone 8 apps that aren’t in the Store? We can think of a couple possible candidates:

  • Pandora
  • Photosynth
  • Molome
  • Facebook  (new version)
  • Viber
  • Skype (new version)

We could throw Instagram on that list, but at this point, we’re not confident at all in that prediction (even though it would be a huge win for the platform).

Photosynth was teased a few weeks ago as nearly complete for Windows Phone 8 and of course Pandora was announced back in October, making those two very likely candidates. Molome, an Instagram-like competitor, is also close to being released.

Have any other candidate apps that you think may be coming? Let us know in comments!
