They say first quarter, but since Apple has some kind of affection with the month of June, I will go with the latter.
Mostly everything that you read about the iPad 2 is speculation. Last year, the iPad was announced on Jan 27th. Until apple announces the date for the iPad 2 , I would not believe the rumors. Also, it is better to check gadgets blog like Engadget for the latest information.
As of right now, no. Every Android tablet on the market right now is using an OS that was designed for the phones, not tablet. There is a high return rate on the Androids (I heard on the tube this week something like 16% to iPad's 2% return rate). Google announced their new OS designed specifically for the tablet, code-named "honeycomb", this week and it is far superior to what is out there right now. With the new iPad due and the new Google OS, I would wait a bit before buying either one. http://tech.fortune.cnn.com/2011/02/02/honeycomb-is-sweet/ I have the iPad right now - it is a decent reader and internet browser and email checker on a portable device, but I can't wait to get my hands on the new Android.
