Google's acquisition of Motorola Mobility last year has raised a new expectation that the company would be coming out with some exciting smartphones in the near future.

One of the most enduring rumors are regarding the Motorola working on the X-phone, which is also claimed as the first smartphone to run the latest Android 5.0 (Key Lime Pie) Operating system. However, it seems that gadget enthusiasts will have to wait long enough to see innovative products from Motorola.

According to The Verge, Motorola's products pipeline are "not really to the standards that what Google would say is wow - innovative, transformative," said Patick Pichette, Google's Chief Financial Officer and Senior Vice President, in Morgan Stanley Technology Conference Thursday.

 "We've inherited 18 months of pipeline that we actually have to drain right now, while we're actually building the next wave of innovation and product lines. We have to go through this transition. These are not easy transitions," he added.

 Motorola recently released smartphones line which includes Droid RAZR Maxx HD and Droid RAZR M. Users of the new smartphones have come up with positive feedback, but Google's most ardent supporters are expecting to see something more. "Since day one, we've started working on the next agenda and we see that pipeline kind of showing up. Our own kind of work is actually quite promising," Pichette said.

Additionally, Pichette also spoke about the feud controversy about Google's current relationship with Samsung. "We have a terrific relationship with Samsung, they've been very successful with Android just like the rest of the ecosystem. We welcome all the partners on our Android platform and continue to innovate," he said.

At Mobile World Congress (MWC) 2013 in Barcelona, Samsung officially announced a new operating system called Tizen. The company also said that it will leave its very own Bada platform for smartphones in favor of the new Tizen OS. However, the South Korean handset manufacturer is the world's number one manufacture of Android-based smartphone. Currently it's two top handsets - The Galaxy S III and the Galaxy Note II, runs on Android OS.
